摘要
利用仿真软件ANSYS FLUENT对装有不同后扰流板的三厢轿车简化模型进行数值模拟,研究了不同截面形状、攻角、定位的后扰流板对汽车空气动力学产生的影响.模拟结果表明,合适的后扰流板形状以及定位能够改变汽车尾流,减小空气阻力和升力,增大下压力,提高汽车的空气动力学性能.
The simulation of the simplified model of the sedan with different rear spoilers is completed by use of ANSYS FLUENT software. The effects of different rear spoiler ＇s position,sectional shape and angle of attack on the sedan aerodynamic characteristics were studied. Simulation results show that suitable rear spoiler shape and installation position can change the sedan wake,decrease air resistance and lift,increase pressure,and improve the sedan aerodynamic performance.
