CFD Approach on Underhood Thermal Management of Passenger Cars and Trucks

This paper presents an analytical methodology developed to enhance passenger cars and trucks cooling and underhood thermal management process utilizing CFD (Computational Fluid Dynamics) technology. Aspects of vehicle frontal openings definition process based on isolated cooling package components airflow requirements are presented as well as the selection and specification of heat exchangers and fans, and the air flux and temperatures distribution management in the engine compartment.
