Fluent Melting and Solidification Essay Example for Free

Fluent Melting and Solidification Essay 8.1 Overview of Phase Change Modeling in FLUENT FLUENT can be used to solve uid ow problems involving phase change taking place at one temperature e.g., in pure metals or over a range of temperature e.g., in binary alloys. Instead of explicitly tracking the liquid-solid front as the phase change occurs, which requires a moving mesh methodology, an enthalpy-porosity formulation is used where the ow and enthalpy equations are solved with extra source terms on the xed grid. Marangoni shear, due to the variation of surface tension with temperature, is important in many industrial uid ow situations involving phase change. The phase change model in FLUENT provides the ability to specify the Marangoni gradient at a sloping surface, as well as an arbitrary shear at a boundary coinciding with one of the curvilinear grid lines. The model also allows you to specify the convective heat transfer, radiation, and heat ux at a wall as piecewise linear pro les, polynomials, or harmonic functions. FLUENT provides the following phase change modeling options: Calculation of liquid-solid phase change in pure metals as well as in binary alloys. Modeling of continuous casting processes i.e., pulling of solid material out of the domain. Chapter 8 | Phase Change Simulations Ability to specify an arbitrary shear at a curved boundary as a piecewise linear pro le or polynomial in terms of one of the Cartesian coordinates. Modeling of Marangoni convection due to the variation of surface tension with temperature. Modeling of the thermal contact resistance between frozen material and the wall e.g., due to an air gap. Ability to patch a momentum source in each Cartesian direction and or a heat source to simulate magnetic force elds or heat generation in the domain, for example. Display and patching of latent heat content, pull velocities in continuous casting and other relevant variables.

Urban Legend of Glenn Dale Hospital :: Ghost Stories Urban Legends

Glenn Dale Hospital Background Over the recent break, I mentioned to a friend that I needed to write about a ghost-related urban legend. He offered to tell me about Glenn Dale Hospital, which is supposedly a famous ghost legend in Maryland. Since I am a lifelong Maryland resident and did not know about the hospital, I was eager to hear the story. The story was told in the living room of a house by a 19 year old white male native to southern Maryland. He is from a middle class family and his father and mother are a construction worker and a homemaker, respectively. He heard the story from another friend who claims to have visited Glenn Dale Hospital. The Story So, in the 30s and 40s they used to send tuberculosis patients to the [Glenn Dale] hospital for treatment. [normal relaxed tone] Eventually it was converted into an insane asylum and it became notorious for its treatment of patients. The staff experimented on the patients and locked them up all day. One day, all the patients revolted and the doctors ran out of the hospital and boarded up all the doors and windows. [talking faster] The patients were left inside to die and the hospital was abandoned. The insane still wander the halls. Today, if you sneak in the hospital you will be chased by the ghosts of the patients and catch tuberculosis. My friend went there and swears he saw a ghost watching him from the shadows, and he won’t go near that place anymore [gestures with hand in horizontal motion]. The cops arrest anyone they catch trespassing, but they say the cops won’t go in the hospital after you if you need help.† Context There is evidence to support some of this story. According to a Washington Post article from December 10, 2006, Glenn Dale Hospital does exist on over 200 acres in Prince George’s County, Maryland. In fact, it did house tuberculosis patients starting in the mid-thirties. However, that is essentially all the truth in the story. The article states, â€Å"It [Glen Dale Hospital] was never an insane asylum, as urban explorers and paranormal researchers suggest on the internet.† Since it was never an asylum, the idea of a revolt and the insane wandering the halls must not be true. Since tuberculosis does not last for decades without human hosts, it is impossible to catch the disease just by exploring the hospital.

Mortar Mixes Using Different Concentration Of MGSO4 Environmental Sciences Essay

1.0 General: Mortar mix is a combination of cement and sand that is used to keep together building type blocks. On adding H2O it becomes a feasible paste that sets difficult. It is used with stuffs like bricks and rocks to do paseos and walls. Mortar was originally made of clay or clay. There is grounds of the usage of howitzer in civilizations around the universe. Persian and Babylonian constructions used howitzer from about 2900 BC on. The earliest Egyptian pyramids used the clay or clay combination, while ulterior edifices used gypsum or calcium hydroxide. Mortar can besides be used for the fix of masonry when the original howitzer has washed off. Modern howitzers are typically made from a mixture of sand, a binder such as cement or calcium hydroxide, and H2O. Cement fabrication is related with a batch of environmental jeopardies and has impacts at all phases of the procedure. These include emanations of airborne pollution in the signifier of dust, gases, noise and quiver when runing machinery and during blaring in preies, and harm to countryside from quarrying, heavy metal emanations in the during the high-temperature calcination procedure of limestone and clay minerals and the ingestion of a immense sum of fuel. Most cement kilns today use coal and crude oil coke as primary fuels, and to a lesser extent natural gas and fuel oil. For the turning population of the universe, the demand for lodging and electricity is besides increasing consequently. For lodging and other installations, the building industry is turning at a really fast gait with of all time increasing demand for cement. To carry through the demand of electricity for such population in India up to 2004 the electricity coevals was about 1,12,058 MW, 65-70 % of which is thermic ( largely coal based ) . Further, harmonizing to an estimation 100,000 MW capacity or more would be required in the following 10 twelvemonth. Concrete is a composite stuff composed of harsh farinaceous stuff ( the sum or filler ) embedded in a difficult matrix of stuff ( the cement or binder ) that fills the infinite between the sum atoms and gums them together. We can besides see concrete as a composite stuff that consists basically a binding medium which particles or fragments of sums are embedded. The simplest representation of concrete is:Concrete = Filler + Binder.There are many different sorts of concrete. For illustration, Portland cement concrete, asphalt concrete, and epoxy concrete. In concrete building, the Portland cement concrete is utilized the most. Therefore, the term concrete normally refers to Portland cement concrete. Admixtures are stuffs other than sum ( all right and coarse ) , H2O, fiber and cement, which are added into concrete batch instantly before or during blending. Use of Admixtures has become a common pattern in modern concrete. Chemical alloies can modify the scene and indurating feature of cement paste by act uponing the rate of cement hydration. Water-reducing alloy can plasticise fresh concrete mixtures by cut downing surface tenseness of H2O, air-entraining alloies can better the lastingness of concrete, and mineral alloies such as pozzolana ( stuffs incorporating reactive silicon oxide ) can cut down thermic snap. 1.1. Mortar: A edifice stuff made by blending calcium hydroxide, cement or plaster of Paris with sand, H2O and sometimes with other stuffs, used in masonry for fall ining rocks, bricks, etc. besides for stick oning. 1.1.1 Gypsum howitzer: The Egyptians used gypsum howitzers in the building of the pyramids. More late, this type of howitzer was used to reconstruct much of the metropolis of Paris, which gave its name to the Gypsum, sometimes called Plaster of Paris, as a consequence of the natural gypsum sedimentations found under the territory of Monmartre. Some of this gypsum bonded masonry still exists in the older parts of Paris. More late, an imported external render, based on Gypsum, originally developed in France, was imported into the United Kingdom. However, after a short period of clip and a bad history of failures this was withdrawn from the market. In add-on to this recent job, it is known that many of the bing historic homes in Paris, that were originally built with gypsum howitzer and have non been restored, suffered severely from moistness and impairment. As a consequence of these inauspicious experiences, and partially originating from the theoretical position that they do non organize hydrates that are stable in presence of H2O, gypsum howitzers are, hence, non used today and non recommended for external work. 1.1.2 Lime Mortars: The Egyptians used lime howitzers, with literature on this topic dating back 2000 old ages. Lime howitzers are believed to indurate and derive strength by the vaporization of H2O and the soaking up of C dioxide from the ambiance. This consequences in the gradual transition of calcium hydroxide into Ca carbonate. This mechanism is theoretically right, but takes a really long clip to bring forth any meaningful strength. 1.1.3 Calcium oxide: The calcium hydroxide is produced, by and large by firing mineral natural stuffs ; dwelling of Ca chiefly but Mg based calcium hydroxides besides exist. Magnesium based calcium hydroxides are non nevertheless used for howitzer in the United Kingdom or Ireland and will non be considered farther in this text. In the United Kingdom, the natural stuffs that are burnt in the kiln to bring forth calcium hydroxide are chalk or limestone, but in theory any chalky feedstock could be used. In some states, shells, corals and other beginnings of Ca are besides used satisfactorily. When the natural stuff, which is fundamentally composing of Ca carbonate, is heated to about 950oC, the combined C dioxide is driven off in the signifier of gas, to ensue in Ca oxide or calcium oxide remaining. 1.1.4 Hydrated calcium hydroxide: Calcium oxide is non used straight in howitzer, but it is foremost reacted with H2O to bring forth Ca hydrated oxide, known as â€Å" quenched † or â€Å" hydrated † calcium hydroxide and in this signifier it is ready to be added in a howitzer mix. However, it is formed that pure Ca hydrated oxide howitzers, though being capable of indurating and strength development, in world it reacts highly easy. Hence, it require a period of possibly 100 old ages for a howitzer articulation to carbonate or indurate to a deepness of possibly 6 to 10 millimeter ( carbonation is the transition of Ca hydrated oxide to calcium carbonate ) . The ancient craftsmen realized this, and knew that a really pure calcium hydroxide was really inferior to one that had some drosss. 1.1.5 Hydraulic calcium hydroxide: When cement is manufactured, calcium hydroxide is burnt in a kiln with clay, to supply a cementing compound that reacts with H2O to bring forth a hard-boiled hydrate. It can be seen that the presence of clay drosss produces efficaciously weak cement. This deficiency of understanding besides leads to an erroneous reading of the belongingss of lime howitzers. Some modern builders and specifies ascribe a whole overplus of good belongingss to â€Å" lime † howitzers, based chiefly on their observations of the long life of historic constructions, without recognizing precisely what type of lime howitzers they do necessitate for their usage. Many successful and long lasting constructions that they believe to incorporate lime howitzers are based on hydraulic calcium hydroxide. In world this is weak and rough cement, when compared to the purer hydrated calcium hydroxides that are produced today. It will be seen that usage of the latter stuff will non bring forth a howitzer with a great trade of strength or lastingness, as the carbonation procedure returns so easy and produces comparatively low strength development. Due to the apparent long permanent nature of hydraulic calcium hydroxide based howitzers, in recent old ages some specifiers have once more been qualifying them, unaware of the manner in which they were produced originally, and in the belief that similar stuffs are readily available today. It is non the instance that hydraulic calcium hydroxides are readily available in the UK today as merely one little works in Dorset produces commercial measures. Some hydraulic calcium hydroxides are imported from Italy and France but whilst these may be echt, a figure are formulated utilizing mixtures of Portland cement, calcium hydroxide and air entraining agent and are therefore non hydraulic calcium hydroxides at all, but instead masonry cements. Study suggests wherever historic calcium hydroxides are referred to these are hydraulic calcium hydroxide in world and non hydrated calcium hydroxide. There are legion illustrations of lasting constructions made with mortar one such illustration of U.K. is illustration Hadrian ‘s wall still which has monolithic restored countries of original stuffs. The Tower of London, some 900 old ages old, provides farther grounds of the lastingness of masonry stuffs and historic calcium hydroxide howitzer. 1.1.6 Ash calcium hydroxide howitzer: The possible pozzolanic belongingss of ash or other stuff incorporating reactive silicon oxides have been known since Roman times. There are many misconceptions and its inappropriate specification. Early bricks were fired at low temperatures and the attendant merchandise was rather extremely reactive in the presence of free calcium hydroxide. However, modern bricks are fired at a much higher temperature and are non about every bit reactive, as earlier one. Therefore a great trade of confusion exists, related to the specification of stuffs which can give a true image of historic features and hence go forthing behind a possible beginning. Therefore, any specification for a lime howitzer to be used in concurrence with land brick dust should be critically questioned. In contrast to the state of affairs with brick dust, the usage of ash in ash calcium hydroxide howitzers has been widespread and more successful, but non to state that these mixes should truly be specified today. After industrial revolution widespread handiness of furnace ashes, ash calcium hydroxide or black ash howitzers are used by common adult male. These stuffs are frequently criticized today, chiefly because of their drosss, taking to lastingness jobs. There is grounds of usage of these stuffs in pit work built around the beginning and center of the 20th century caused corrosion of the wall ties, but it is ill-defined whether or non many of these ties would hold corroded in any event regardless of the type of howitzer used. Many constructions exist today besides where old ash calcium hydroxide howitzers are still lasting. Ash lime howitzers were still used good into the center of the 20th century in those parts of the state where ash was widely available. 1.1.7 Cement: calcium hydroxide: sand howitzers: Development of â€Å" modern † Portland cements, the potency for masonry building. This is attributable rapid rate which enabled building work. The early limes antecedently used produced acceptable working belongingss for the Masons. The rate of strength addition was low, particularly in cold conditions conditions. This meant that even a high quality calcium hydroxide, with a good ultimate strength, could turn out really debatable for winter use. Indeed it is likely that the bulk of masonry building proceed small during the winter months. The handiness of the new Portland cements changed this state of affairs and enabledConstruction to transport on throughout the twelvemonth, with the obvious exclusion of periods of really terrible winter conditions with heavy precipitations or stop deading temperatures. However, a job arose with these new stuffs. With the calcium hydroxides, which they antecedently worked with, mix proportions of between one portion binder to two or two and a half parts sand ( 1:2 and 1:2 ) were used by the Masons. These mix proportions produced a mix with acceptable working belongingss. The usage of such high binder contents with cements resulted in a howitzer was excessively strong for the units for which it was being applied. Use of these stuffs for reconstructing the earlier work suffered from some short comings.Solution to this job was to utilize both calcium hydroxide and cement as a binder, with the calcium hydroxide and cement together organizing the proportions of one portion of binder to two and a half or three of sand.Today, howitzers are widely used in most continents, preponderantly in Europe, North America, Australasia and Asia. 1.1.8 Masonry cement howitzers: Use of Masonry cement howitzer in a cement plant is an alternate construct of blending together cement and calcium hydroxide on site or to obtain a blend of the belongingss of howitzer which is neither excessively strong nor excessively weak. Recent research work has shown that limestone may besides supply an enhanced strength development in the medium and long term because of a slow continuance of the cement hydration/strength development procedure. In United Kingdom masonry cement is utilized as mixtures of Portland cement and crushed rock, wherever in North America, the tradition has been to utilize mixtures of Portland cement and hydrated calcium hydroxide, together with air entrainment. This construct has late been adopted by one of the UK cement plant and has now been incorporated into the Code of Practice BS 5628. 1.2. Coal: Coal occupies an of import place in the Indian energy sector since India has huge militias of thermic class coal. Coal is the most abundant and widely dispersed dodo energy resource in the universe. Among the entire power generated yearly in India, approximately 70 % is produced by thermic power workss. The bulk of thermic power workss ( about 84 % ) are running on coal with 70 billion dozenss of coal modesty, while the staying 13 % tally on gas and 3 % on oil. About 112 million dozenss of fly ash is generated yearly in India by thermic power workss as a byproduct of coal burning. Fly ash is a burnt and powdery derived function of inorganic mineral affair that generates during the burning of powdered coal in the thermic power works. The burned ash of the coal contains largely silica, alumina, Ca and Fe as the major chemical components. Depending on the combustion temperature of coal, the mineral stages in crystalline to non-crystalline constructions such as vitreous silica ( SiO2 ) , mullite ( 3Al2O3.2H2O ) , hematite ( Fe2O3 ) , magnetite ( Fe3O4 ) , wustite ( FeO ) , metallic Fe, orthoclase ( K2O Al2O3.6SiO2 ) and fused silicates normally occur in the burned coal ash. Silica and alumina history for approximately 75 to 95 % in the ash. The categorization of thermic works fly ash is considered based on reactive Ca oxide content as class-F ( less than 10 % ) and class-C ( more than 10 % ) . Fly ash quality depends on coal type, coal atom choiceness, per centum of ash in coal, burning technique, air/fuel ratio, and boiler type. Indian fly ash belongs to class-F. The Ca bearing silicon oxide and silicate minerals of ash occur either in crystalline or non-crystalline constructions and are hydraulic in nature ; they easy reacts with H2O or hydrated lime and develops pozzolanic belongings. But the crystalline mineral stages of vitreous silica and mullite nowadays in the ash are stable constructions of silicon oxide and silicates, and are non-hydraulic in n ature. Normally the fly ash contains these two mineral stages as the major components. Therefore, the use of fly ash in building industry as sums or replacing of cement mostly depends on the mineral construction and pozzolanic belongings. Fly ash is loosely an aluminium-silicate type of mineral rich in aluminum oxide and silicon oxide. 1.2.1.Worldwide Scenario of fly ash Use: Indian coals have really high ash content. The fly ash content of coal used by thermic power workss in India varies between 25 and 45 % . A big sum of fly ash is generated by thermic power workss, doing several disposal related jobs. In malice of enterprises taken by the authorities, several non-governmental and research and development organisations for fly ash use, the degree of fly ash use in the state was estimated to be less than 10 % anterior to 1996-97.On the Global degree, less than 25 % of the entire one-year fly ash produced is utilised. However, in many states like Germany, Belgium and Netherlands more than 95 % of the entire fly ash produced was reportedly used during 1996. Likewise United Kingdom 50 % fly ash was utilized during 1998, whereas the use by the China during 1995 was about 32 % and 40 % , severally. European states are taking in use of fly ash. In Canada a batch of research work has been done in the country of high volume fly ash concrete and they are efficaciously utilizing fly ash since last two decennaries. Japan is besides front smuggler in use of fly ash in Asia. The use of fly ash by twelvemonth stoping 2001-2002 is given below: Germany & A ; Netherlands: 100 % Belgique: 90 % Japan: 67 % India: 13 % 1.2.2. Leaching Behaviour of fly ash: In India, surveies have been carried out toward direction of fly ash disposal and use. Fly ash is utilized in cement and building. But, the rate of production is greater than ingestion. The fresh fly ash is disposed into keeping pools, lagunas, landfills and slagheaps. Disposal of immense sums of fly ash in landfills, and surface impoundings or its reuse in building stuffs is of environmental concern. LeachingA is the motion of contaminations, such as water-soluble pesticides or fertilisers, carried by H2O downward through permeable dirts. Most pesticides adsorb to dirty atoms ( particularly clay ) become immobile and do non leach. The destiny of nomadic pesticides, nevertheless, can be thought of as a race between the assorted debasement procedures and leaching to groundwater. During conveyance, disposal, and storage stages, fly ash is subjected to leaching and portion of the unwanted constituents in the ashes may foul both land and surface Waterss. Fly ash can be leached in higher concentrations than imbibing H2O criterions and can do taint in imbibing H2O beginnings. Fly ash contains trace sums of toxic metals that may hold negative effects on human wellness and on workss. Disposal of fly ash in surface H2O beginnings disrupts aquatic life, whereas toxic metals leached contaminate belowground H2O resources. Therefore, it is of import to analyze the leaching behavior of fly ash. In India, so far non much accent has been given to utilize coal ash as backfill stuff in underground/ unfastened dramatis personae mines and to foretell its subsequent consequence on land H2O quality. One of the chief jobs in disposing of large measures of coal ash is the possible leaching of different pollutants. A thorough probe sing leaching of trace/heavy metals from different fly ashes is required to cognize the impact of leached hint metals from fly ash to land H2O every bit good as surface H2O. In the present survey, short term and long term leaching survey has been carried out on fly ash from Panipat Thermal Power works, Haryana. An effort has been taken to analyze the leaching behaviour of fly ash as per the internationally recognized process laid down inCEN/TS 14405. 1.3. Objective of Work: The chief aim of the present research work is twofold. The first 1 is to utilize the fly ash as cost effectual replacement of dearly-won building stuffs and 2nd 1 is to happen out the optimal workability and public presentation of howitzer mix with fly ash in inauspicious commixture and hardening conditions. A typical research programme formulated for the survey is shown in Table 1 & A ; 2. In the capital metropolis of Delhi, the sanctum River Yamuna is the chief beginning of H2O. The usage of natural Yamuna H2O for building proposes is how far good and, if non, how much impact it put on the overall public presentation of howitzer regular hexahedrons in the similar commixture and bring arounding status with that of the normal DJB H2O supplied for imbibing intents has been attempted for comparing. In add-on to the above, leaching column survey on fly ash collected from NTPC, Panipat has besides been performed for appraisal of likely leaching of hint elements as per standard process laid down in European Standard CEN/TS 14405.Table 1.1: Research on howitzer mixes utilizing Yamuna H2O with different concentration of MgSO4 for blending and DJBW & A ; YW with different concentration of MgSO4 for bring arounding of howitzer regular hexahedrons.Mortar mixes utilizing different concentration of MgSO4 in Yamuna H2OYamuna H2O4 % MgSO48 % MgSO412 % MgSO416 % MgSO4Water quality for hardening of howitzer regular hexahedronsNormal DJB H2OYamuna H2O4 % MgSO4DJB Water8 % MgSO4 DJB Water12 % MgSO4 DJB WaterDetailed periodic surveies for physical, chemical and mineralogical surveies of H2O and concrete7 yearss7 yearss7 yearss7 yearss7 yearss28 yearss28 yearss28 yearss28 yearss28 yearss56 yearss56 yearss56 yearss56 yearss56 yearss90 yearss90 yearss90 yearss90 yearss90 yearss365 yearss365 yearss365 yearss365 yearss365 yearssTable 1.2: Research on howitzer mixes utilizing 35 % Yamuna H2O with different concentration of MgSO4 for blending and DJBW & A ; YW with different concentration of MgSO4 for bring arounding of howitzer regular hexahedrons.Mortar mixes utilizing 35 % fly ash with different concentration of MgSO4 in Yamuna H2ODJB H2O4 % MgSO48 % MgSO412 % MgSO416 % MgSO4Water quality for hardening of howitzer regular hexahedronsNormal DJB H2ONormal Yamuna H2O4 % MgSO4DJB Water8 % MgSO4 DJB Water12 % MgSO4 DJB WaterDetailed periodic surveies for physical, chemical a nd mineralogical surveies of H2O and concrete7 yearss7 yearss7 yearss7 yearss7 yearss28 yearss28 yearss28 yearss28 yearss28 yearss56 yearss56 yearss56 yearss56 yearss56 yearss90 yearss90 yearss90 yearss90 yearss90 yearss365 yearss365 yearss365 yearss365 yearss365 yearssDue to the increasing demand of energy, the rate of production of fly ash is besides increasing. The use of fly ash in cement or building industry is non in synchronism with the immense sum of its production. The safe disposal of fly ash is a topic of concern as fly ash poses risky jobs to the environment in many ways.The fresh fly ash is disposed into keeping pools, lagunas, landfills and scoria tonss. Fly ash can pollute the surface H2O, dirt and besides the land H2O due to the leaching of unwanted constituents. Fly ash can be leached in higher concentrations than the prescribed bounds of codifications for imbibing H2O criterions and can do taint in imbibing H2O beginnings. Fly ash contains trace sums of toxic metal s that may hold negative effects on human wellness and on workss. Disposal of fly ash in surface H2O beginnings disrupts aquatic life, whereas toxic metals leached contaminate belowground H2O resources. Therefore, it is of import to analyze the leaching behavior of fly ash. 1.4.
