EFFECTS OF CAR INCLINATION ON AIR FLOW AND AEROTHERMAL BEHAVIOR IN THE UNDERHOOD COMPARTMENT

摘要

The study presented here concerns the impact of car inclination on the temperatures in the vehicle underhood compartment. We report here underhood thermal measurements carried out on a vehicle in wind tunnel S4 of Saint-Cyr. The underhood is instrumented by 80 surface and air thermocouples. Measurements are carried out for three thermal functioning points: the engine in operation and the front wheels positioned on the test facility with power-absorption-controlled rollers. Three car inclinations are tested.
