摘要
采用3种不同方法,利用计算流体力学软件FLUENT对侧风状态下轿车的气动特性进行了数值模拟,得到了不同侧风状态下轿车气动阻力系数和侧力系数随横摆角而变化的曲线。讨论了不同方法的优缺点并将模拟结果与风洞实验进行对比,结果表明采用合适的数值模拟方法可省时省力地获得接近于实验的结果。
By adopting 3 different schemes and using CFD software FLUENT, numerical simulations on the aerodynamic characteristics of a car under crosswind conditions are conducted, and the car aerodynamic drag and side force coefficient curves as the functions of yaw angle under different crosswind conditions are obtained. The advantages and drawbacks of different schemes are discussed and the simulation results are compared with that of tunnel experiments. The results show that adopting appropriate numerical simulation scheme can get a result close to experiment with least time and efforts.
