Paper Details

he thermal conductivity of heating or cooling fluids is a very important property in the development ofenergy-efficient heat transfer systems. Thermal conductivity of the fluids is one of the basic properties taken into accountin designing and controlling the process. Automobile radiators are becoming extremely important in terms ofperformance of vehicle and maximum heat dissipation, also they are highly power-packed with increasing power toweight or volume ratio. The flow behaviour & temperature profile prediction in the radiator tubes are very usefulinformation & is of great importance to the designer. CFD is very useful tool in accessing the preliminary design andperformance of the radiator. In this paper, the model was done Pro-E software and imported in ANSYS-12. The analysiswas done in CFX for three different coolants considering helical tube configuration. The coolants considered wareEthylene Glycol, Propylene Glycol & Methanol. The overall pressure & temperature distribution of the co olant wasevaluated for helical tubes used in radiator. There were taken two pitch of Helical tubes as 15mm & 20 mm Pitch.Methanol in the helical tube radiator has got maximum temperature drop compared to Propylene Glycol & EthyleneGlycol. Compared to 15mm Pitch & 20mm Pitch Helical tube Radiator, 15mm Pitch Helical tube used in radiator ismore heat dissipation compared to 20mm Pitch Helical tube used in Radiator.
