发动机舱热分析问题（en）

Thermal Protection is of vital importance in the development of passenger cars. In the last years thermal issues have been increasingly investigated by numerical means. Computational fluid dynamics (CFD) is today an efficient way to optimize the aerodynamics of a new car or to investigate the underhood flow, especially the mass flux through the heat exchanger package. Additionally the computation of underhood flow field and air temperature distribution is today common practice. This allows, for example, an engineer to judge the performance of the engine fan and vents as well as look for hot air spots within the underhood.
