Abstract The European Commission (EC) as well as the United States Environmental Protection Agency (EPA) published legislations to regulate vehicle related emissions to reduce greenhouse gas emissions in order to reduce global warming. The Worldwide harmonized Light vehicles Test Procedure (WLTP) defines a global harmonized standard for determining the fuel consumption of passenger cars and light commercial vehicles. Thermal management of the powertrain lowers fuel consumption during the warm-up phase by getting quicker to operating temperature. An efficient heat flow distribution requires components optimized for thermal management. This paper will investigate various optimization potentials for a standard engine coolant radiator used in mid-sized vehicles. A radiator optimized for heat transfer as well as packaging was used as a baseline radiator. Factors considered include heat transfer, coolant side pressure drop, air side pressure drop, and packaging of this radiator optimization. Main target was to optimize coolant pressure drop of the radiator without compromising heat transfer performance nor air pressure drop. This paper further reviews the test results obtained by this study, describes the applied approach for Computer Fluid Dynamics (CFD) and the selected parameters for the Design of Experiment (DOE).
