摘要
对某汽车车身外流场进行仿真分析,针对其存在向上空气升力的问题,提出尾部增加扰流板的改进方案,并对改进方案进行仿真分析。结果表明,改进后的汽车空气动力学性能得到改善。
The authors simulate and analyze the external flow field of a vehicle body. According to the problem of upward pneumatic lift existed on the vehicle body,they put forward a improving scheme of adding the rear spoiler at the vehicle body tail and simulate and analyze the improved scheme. The results show that the aerodynamic performance of the improved vehicle gets improvement.
