Thermal Analysis of Car Radiator by using Nano Fluid

During the conversion of fuel energy to mechanical energy by combustion, for casual engines approximately one-third of the energy goes to mechanical energy, one-third goes to exhaust heat and one-third goes to cooling system heat load .The limitations of fossil fuel in the world, optimizing energy consumption in various industrial processes becomes very important. In chemical process one of the most important devices related to energy and heat transfer is the heat exchanger. For decades, efforts have been done to enhance heat transfer, reduce the heat transfer time, minimize size of heat exchangers, and subsequently increase energy and fuel efficiencies. These endeavors incorporate and dynamic strategies, for example, making turbulence, expanding territory, and so forth. The majority of them are constrained by innate limitation of heat conductivity of the traditional liquids (for example, water, mineral oil and ethylene glycol).The poor heat transfer properties of the employed fluids in the industries are obstacles for using different types of heat exchangers. The heat rejection requirements of automobiles are continually increasing due to trends towards more power output for a given engine size, increased air conditioning and additional Auxiliary equipment. But the cooling requirements under some special work conditions could no longer be met merely by improving the structure of engine cooling system.
