Automobile radiators are most important part of the heavy & medium vehicle. The flow behavior &
temperature profile prediction in the radiator tubes are very useful information & is of great importance to the designer.
CFD is very useful tool in accessing the preliminary design and performance of the radiator. In this paper, the model
was done Pro-E software and imported in ANSYS-14.5. The analysis was done in CFX for helical tube configuration. The
coolant considered as an Ethylene Glycol. The overall pressure & temperature distribution of the coolant was evaluated
20mm pitch helical tube used in radiator. From analysis, Mass flow rate very important role during heat transfer
process. Analysis done with different mass flow rate & coolant used as ethylene glycol & we taken value of inlet
temperature & outlet temperature, as well as inlet pressure & outlet pressure. From this value & graph derived that with
decreasing mass flow rate; Temperature drop continuously increases & pressure drop continuously decreases. That
means with decreasing mass flow rate we get more cooling effect & also friction decrease.
