Abstract
The passenger car thermal management is studied in this chapter by simulation method. The underhood air flow is simulated by CFD in order to optimize engine cabin layout. The whole cooling system is modeled by 1D flow simulation in order to matching the critical components in the system. The thermal analysis is carried out by the coupling of 3D CFD and 1D simulation including radiation. The two type of gasoline engines -naturally aspirated (V6 PFI 3.0L) and turbo-charged direct injection (TGDI 2.0L) are layout in the same car underhood separately, and both have good thermal management performance. The thermal balance test and temperature measurement are carried out in order to validate the simulation.
