Paper Details

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 modelwas done Pro-E software and imported in ANSYS-14.5. The analysis was done in CFX for helical tube configuration. Thecoolant considered as an Methanol. The overall pressure & temperature distribution of the coolant was evaluated 20mmpitch helical tube used in radiator. From analysis, maintain of outlet pressure of radiator is very important role duringheat transfer process. Analysis done with different outlet pressure of the radiator & coolant used as Methanol & wetaken value of constant inlet temperature & variable outlet pressure. From this value & graph derived that with takingdifferent outlet pressure of radiator; maintained outlet pressure is very important role during heat transfer process. Foranalysis we taken mass flow rate 0.5 kg/sec & different outlet pressure of coolant like 0.25, 0.5, 0.75, 1.0, 1.5, 2.0 bar.We received result as a temperature difference between inlet temperature & outlet temperature of header of tube, whichare 28.52, 31.25, 30.51, 33.25, 19.52 & 1.75, & Pressure difference like 0.43, 0.42, 0.42, 0.42, 4.0 and 124778 withrespect to increasing outlet pressure of radiator. At outlet pressure 2 bar, we getting temperature difference only 1.75 &pressure difference 124778 which is not desirable. From analysis we have getting best result at Outlet pressure 1 barwith temperature drop 33.35 & pressure drop 0.42 bar.
