中文摘要：
采用多种常用的湍流模型和CFD软件Fluent对背倾角为25°的Ahmed模型外流场进行模拟,并与风洞试验和大涡模拟结果进行比较。结果表明,对于升力系数,在有限计算资源的条件下采用Realizablek-ε模型能获得相对较好的结果,最后采用Realizablek-ε模型对某实际车型进行模拟,得到了令人满意的结果。
英文摘要：
Several common turbulence models and CFD software Fluent are used to conduct simulations on the external flow field of an Ahmed model with a back slant angle of 25°,and the results are compared with those of wind tunnel test and large eddy simulation.The results show that,for lift coefficient,using Realizable model can get relatively good result under limited computing resources.In the end,Realizable model is applied to the simulation on a real car with satisfactory results obtained.
