HEAT TRANSFER CHARACTERISTICS OF VARIOUS FLUIDS

The study aims to provide knowledge about the heat transfer characteristics of five different fluids are water, carbon nanofluid, a mixture of ethanol and water, a mixture of methanol and water, a mixture of ethylene glycol and water using a heat exchanger setup which was fabricated for the desired study with the water as the hot fluid in every case studied.This study helps to choose the best coolant out of the tested ones which can be used to cool the components, systems that dissipate heat during its functioning which has to be removed to prevent the failure of the components. Test Section has a cuboidal shell where the hot fluid is filled and copper pipe through which coolant flows. The coolant is circulated and the temperature of the hot fluid in each case is plotted against time on the graph.More the temperature difference better will be the fluid corresponding to that difference as we want more heat to be extracted from hot fluid and losses are neglected as insulation is provided outside shell. As heat is to be dissipated for the proper functioning of components, this forced us to think and research more thoroughly to get in-depth knowledge.
