Buoyany Driven Flows in a Thermocline Cylinder with Sensible Heating
Buoyany Driven Flows in a Thermocline Cylinder with Sensible Heating 1.0 Introduction Buoyancy driven ﬂows, especially within enclosures, has been of great interest over the last 10 years. Buoyancy-driven natural convection in a heated cavity with differentially heated walls, maintained at a constant temperature, is a model for many industrial applications. One of the complexities of a flow within a cavity is the characteristic interplay of both the viscous and buoyancy forces of the fluid. Therefore, many experiments and numerical simulations have been reportedly conducted, in order to gain a better understanding of the flow and its properties. Rayleigh number, a dimensionless fluid property, dictates the buoyancy-driven ﬂow within a cavity, which arises due to differences in gradients of the fluid. This is a model problem for many industrial applications e.g. heat recovery systems, energy-eﬃcient design of buildings and rooms, gas-filled cavities around nuclear reactor cores, methods of cooling electronic devices, double glazed windows and solar energy instruments (i.e. thermal energy storage systems [thermocline tanks]). This research paper presents a numerical analysis of a thermocline tank, modelled as a square 2D cavity with differentially heated vertical walls. A commercial CFD package will be used to obtain solutions for the heat transfer of the two-dimensional natural convection flow model and express it in terms of global and local Nusselt numbers. 2.0 Literature review The reliance upon fossil fuels for power generation coupled with an inadequate energy storage system has led to having the environmental concerns we currently observe. Being able to capture and store Carbon Dioxide has been extremely useful however, recently there has been an advancement in the energy sector. The storage of thermal energy as sensible heat in a thermocline cylinder has provided a platform for concentrated solar power (CSP) plants to generate electricity throughout the night without the use of fossil fuels. With a development and utilisation of renewable energy sources in the energy sector, solar power has become increasingly popular as an alternative source of energy which can provide a considerable amount of power if utilised and optimised appropriately. It is estimated that the sun can provide solar energy for another 4 billion years, making this source of energy sustainable and renewable in the long-term (Davison, 2018). Thermal energy storage has a growing role in global deployment of power generation from solar power, due to their inherent intermittent nature. 2.1 Concentrated Solar Power (CSP) Concentrated solar power (CSP) plants are anticipated to increase their presence in electricity markets, specifically because of their ability to integrate cost-effective thermal energy storage (TES) and create high efficiencies with notable scale up potential. When applied to concentrated solar power plants, thermal energy storage may allow for electricity generation at periods of limited sunlight i.e. nocturnal periods, which can correct the disparity between supply and demand. Traditionally in CSP plants, a tank storage system is implemented, where a heat transfer fluid acts as the primary heat storage medium in either one or two tanks (Alva, Lin and Fang, 2018). The two-tank system can be configured as an indirect or direct system, where the biggest difference between them both is the heat transfer fluid (HTF) used in both the TES and solar field. For an indirect system, the working HTF within the TES is different to that of the HTF being pumped through the solar field. Due to this difference in the fluids, there is a requirement for an intermediate heat exchanger to facilitate heat transfer between both HTF. So, throughout daylight operations, the solar field HTF transports the gathered solar thermal energy to a power block, where there is a steam generating heat exchanger (i.e. boiler) and the surplus thermal energy is transferred to the TES HTF via the intermediate heat exchanger. The direct system works by using the same HTF for both the solar field and TES, therefore it does not require an intermediate heat exchanger. In the two-tank system, hot (heated) HTF is stored in one tank and cold HTF is stored in the other, so there is a temperature difference between them both. (Fasquelle et al., 2018) 2.2 Alternative storage options The other storage method which is becoming increasingly popular in CSP plants is the use of a one tank system, called a thermocline tank. This storage method operates based on having fluid at dissimilar temperatures in the same tank. Due to temperature differences in the fluid, there is differences in the density between them both. Therefore, the higher temperature (less dense) fluid rises to the top of the tank and the colder, denser fluid falls to the bottom of the tank. There is an intermediate layer formed between the hot and cold fluid, which is called a thermocline, hence the name ‘thermocline’ tank. This method of storage has many benefits, the obvious one being the need for just one tank rather than two, which will reduce costs by up to 35% in comparison to a two-tank storage configuration. (Tesfay and Venkatesan 2013). All possible configurations for single tank and two-tank thermal energy storage systems can be seen below in figure 1. Figure 1: CSP plant configurations; (a) Indirect two-tank set up, (b) Single tank thermocline storage with heat exchanger, (c) Direct storage two-tank set up, (d) Single tank thermocline storage (direct) [Biencinto, M. et al. (2014)]. There have been different heat transfer fluids used in the past but the most common one used for recent studies is molten salt. This is because of some advantages which molten salts possess, they can raise the solar field output temperature to approximately 450-500°C, in so doing, this can increase the Rankine cycle efficiency of the power block steam turbine to ~ 40%. In comparison, the current high-temperature oil cycle efficiency is around 37.6% with an output temperature of 393°C. Kearney, D. et al. (2003). 2.3 Heat Transfer Mechanism Heat transfer can be of three modes, conduction, convection and radiation. The heat transfer mechanism relies on temperature differences between systems as the driving force. Heat energy will move from a region of higher temperature to a region of lower temperature until there is equilibrium of the temperatures in the respective systems. Conduction Heat conduction can occur in solids, liquids and gases. The heat energy is transferred from high-energy particles to low-energy particles within the system as the particles interact with each other. These interactions differ dependent upon the fluid state interactions. For example, in solid state systems conduction occurs as the heat transfer is carried out by the vibration of molecules and the energy transport by free electrons. However, in liquids and gasses, the heat conduction occurs due to the collisions and diffusion of the molecules by their random motions. Heat conduction is affected by two factors: the thickness and the density of the medium. So, at constant temperature conditions, the thickness of the medium will affect the heat energy that is transferred i.e. a thicker medium would allow less heat transfer and vice versa. Therefore, the thermal conductivity of gas is lower than liquids as the molecules of liquids are more closely spaced than gases. Based on these facts, we can conclude that the amount of heat transfer via conduction is proportional to the temperature differences across the medium but is inversely proportional to the thickness of the medium, this is equation is known as Fourier’s law of heat conduction; Qconduction= –kAdTdx Where; A= Surface area, k= Thermal conductivity of material/substance, dTdx = Temperature gradient across medium Convection The heat convection mechanism occurs across fluid mediums and the integral feature for the heat transfer to occur is the motion of the fluid i.e. bulk movement of fluid particles. This mode of heat transfer can only take place across a temperature gradient and the equation that describes this is known as Newton’s law of cooling, which is; Qconvection=hA(Tf–T) Where; h= Convective heat transfer coefficient, A= Surface area, Tf = Temperature at the surface, T= temperature of surrounding fluid Convection can be split into two groups, forced convection and natural convection. As the name suggests, in forced convection the fluid motion is driven by an external force, whereas in natural convection, the fluid motion is driven by natural effects, such as buoyancy driven forces. Buoyancy driven forces are a phenomenon whereby a lighter fluid gravitates upwards due to a net vertical force in a gravitational field. When heat energy is transferred from a solid substance to adjacent fluid substance via convection, the fluid will warm up and become relatively light. This light fluid will experience weight loss as the result of reduced gravity and gravitate upwards, whilst a cooler, more dense fluid will move downwards; this is then known as the buoyancy driven force. Fluid properties such as the Nusselt number (Nu), is the parameter which expresses the ratio of convective to conductive heat transfer ratio, which is the single most important parameter when looking at heat transfer configurations. Another important fluid property is the Rayleigh number (Ra), which is associated with buoyancy driven flows within fluids when natural convection is occurring. When a critical Ra value specified for a fluid is surpassed, the main mode of heat transfer occurs through convection. Equation 1- Rayleigh number- Taken from [Iacovides, H. (2018).] Equation 2- Nusselt number- Taken from Iacovides, H. (2018). Other important dimensionless parameters are; the Reynolds number (equation 3), the Prandtl number (equation 4) and the Grashof number (equation 5). They represent the ratio of inertial force over viscous force (eq 3), the ratio of viscous diffusion over thermal diffusion (eq 4) and the ratio of buoyancy force over viscous force (eq 5). All five of these dimensionless parameters mentioned, play a crucial role in governing the physics of the flow. Equation 3- Reynolds number- Taken from Iacovides, H. (2018). Equation 4- Prandtl number- Taken from Iacovides, H. (2018). Equation 5- Grashof number- Taken from Iacovides, H. (2018). 2.4 Modelling
World Starvation Essay
essay helper free Introduction The issue of world starvation is real in this millennium. So many people are facing starvation. The Food and Agriculture Organization (FAO) puts the figure to about one billion of the people facing starvation in 2010. The statistics for hunger are troubling with about 18, 000 children dying everyday of hunger related issues (FAO 1). In 2005, about 1.4 billion people were in extreme poverty. The World Bank estimated that food prices would shoot up in 2008 and following the recent global down turn the prices have escalated pushing more people into poverty and thus hunger. The challenge of hunger or food insecurity is enormous in areas within low incomes areas. Finding a solution to world starvation is not an easy one because the number of undernourished people is very high. Scientists and policy makers have been working in the area of food technology to help overcome with the problem of world hunger. In 2010, the number of undernourished people declined due to a slight improved economy especially in the developing nations. Moreover, food prices have fallen from the high prices experienced in 2008. FAO puts the undernourished at 925 million this year compared to 1.023 billion in 2009 as shown in figure below. Source: FAO Most of the gains were made in Asia where there were 80 million less hungry. In sub-Saharan Africa the number reduced by 12 million. Nonetheless, the number of the hungry is still very high due to the current world economic situation, poverty, famine and conflict and a solution is needed to improve food security in the world and more so in areas with chronic food crises. Food technology Developments in food technology have enabled many people to access food. The life span of human beings has also increased in many parts of the world because the people have food that has improved their life quality. The developing nations have not been left behind and life span has risen in the recent decades. Get your 100% original paper on any topic done in as little as 3 hours Learn More The advancement made in food technology has helped to feed the high world population due to high grain production. Scientists working in the food and technology field have come up with various ways of increasing food production. New ways of feeding the world population have been developed such as genetic engineering and biotechnology (Prakash and Conko 1). These methods are aimed at improving food security. Genetically modified foods Genetically modified foods have been introduced in a bid to curb world starvation. Through genetic modification, foods and animals are modified through the manipulation of genes to yields the best possible yields according to the needs of human beings. Moreover, crops can be modified to make them more resistant to pests and thus protect them to ensure good yields. Agricultural technologies in developed countries Farmers in the countries that have embraced food technology and in particular genetically modified foods are now able to produce double of the grains they were producing in the same size of land. The genetically modified foods ensure good produce and mature faster than the conventional crops. Countries especially the developed ones have embraced genetically modified crops and for example in the United Kingdom genetically modified crops such as soya, maize, tomatoes and cheese have been approved (Jones 1). The United States has approved a wheat has also embraced genetically engineered food and currently the debate on the approval of genetically modified salmon is ongoing. However, not everyone has embraced genetically modified foods due to healthy and safety concerns. Some people have fears about the safety of genetically modified foods because some are said to be harmful. Thus, people have to be educated about the use of genetically modified foods to array the fears they have and to use them to supply their nutritional needs. Scientists have across the globe “have attested to the health and environmental safety of agricultural biotechnology” and they call for its use especially by countries that have major hunger problems (Prakash and Conko 1). Many health and scientific organizations have endorsed biotechnology for example, the American Medical Association and the United Kingdom Royal Society. Agriculture technologies in Africa Agricultural technologies have helped to improve food security for many countries. Thus, efforts are being made to encourage African countries embrace agricultural technologies. We will write a custom Essay on World Starvation specifically for you! Get your first paper with 15% OFF Learn More There is need for African nations to embrace food technology because most of the poor people live in rural areas in the developing countries. Africa cannot afford to ignore agricultural technologies to improve its food production to feed its high population. The continent is a major importer of grains and its grain production has remained at the same level for over four decades (McPherson 5). The African leaders have taken a step towards reversing this trend. The first step they have taken is to pledge to increase the budget allocated to agriculture. The increased budget will help the farmers in the rural area produce adequate food for their consumption. The money allocated in the budget will go a long way in aid research to come up with food varieties that are suitable for the African climate. Use of synthetic pesticides and fertilizers Fertilizer and pesticide use is crucial in agriculture. The cost of fertilizer is high and many African governments have taken a step in making fertilizers available to the farmers through subsidies. Other steps have been by working in conjunction with banks to provide farmers with loans to secure fertilizers for instance the Equity Bank in Kenya. Malawi is a success story in adapting food technologies to improve its food production, which has made it a breadbasket for South African region. The government gave farmers subsidy in buying fertilizers and many farmers attributed the 2007 bumper harvest to government’s effort (Dugger 2). Green revolution in the Caribbean and Latin America The green revolution in Latin American and Caribbean has led to increased food production. These two regions have been able to provide food for their population even though about 55% live in the rural area in poverty in a region that is richly endowed with natural resources (Izquierdo and De la Riva 1). The region has failed to produce adequate food to feed its population due to desertification, floods, soil erosion among other factors. Therefore, it is important for the region to embrace food technologies that will help the region to feed its population. The region has applied agricultural technologies more vigorously because earlier on only a few applications food technologies were utilized. The region has realized that it cannot continue to depend on the success of the green revolution to provide food because the method cannot bring in the success required to feed the whole region. Biotechnology methods must be adapted to reduce the dependence on imports for the provision of basic grain needs for the population. In this regard, FAO has come up with a program called the Special Program for Food Security (SPFS) to assist countries to increase their food productivity. The program will help the region to improve and develop their biotechnology because in the past the kind of agricultural technologies applied have not been successful because they failed to address the unique needs of the region (Izquierdo and De la Riva 1).

The technology will help to solve the problem of crop pest infestation and increase crop yields. The methods applied in biotechnology will help to come up with crops that can withstand the current environmental conditions such as drought resistant crops. So far, many people have benefited from genetically modified crops grown across sixteen nations in the world. Many farmers in the developed countries have benefited from the agricultural technologies in the less developed countries. The adaption of food technology in the developing countries shows that these technologies can be transferred and used in countries that are less industrialized just like in the developed countries (Prakash and Conko 1). Using agricultural technologies will enable the countries in many parts of the world to gain food security. A world with adequate food will give the people an opportunity to live full quality lives and improve their economic status. As long as people have adequate food supply they will be in a position to produce grains to ensure that, all year round they have food because hungry people cannot be in a position to produce food. Having adequate food to feed the undernourished and the people facing starvation will help to reduce the number of deaths that occur daily while a few millions are overfed.
