| Abstract: | This paper presents the correlations of underhood thermal management test and simulation.We tested the cooling air velocity and flux through the condenser and radiator at three cases of idle,maximum torsion and 70% max speed,and progressed the correlation of test and simulation.The rotating fan is one of the important causes that affect the simulation result.The necessary conditions are given that ensure the engine cooling. |
