Optimization of Front-End Cooling Module for a Commercial Vehicle Using a CFD Approach

From 2012 Automotive Simulation World Congress: This presentation describes the effects of design actions using ANSYS Fluent on engine cooling performance of a commercial vehicle. The resistance of heat exchangers is considered using a porous modeling technique. The outlet temperature of intercooler charged air and radiator coolant is predicted along with amount of heat rejected by the intercooler and radiator. Air flow rate and air temperature at the entry and exit faces of intercooler and radiator are also predicted. This analysis helps to identify the air flow pattern in underhood and underbody regions for three vehicle conditions: idling, max torque and max power.
