摘要
采用GAMBIT软件作为前处理器,应用FLUENT软件作为计算和后处理软件,对不同进出风模式和电池组位置的电动汽车气动性能进行分析,研究表明:单口上出风模式的电动汽车气动性能最佳,下出风口模式的气动性能最差;随着电池组与动力舱后壁距离增加,电动汽车气动性能先改善,再变差,满足电动汽车最优气动性能的距离为230mm.
Using software GAMBIT as pre-processor and software FLUENT as calculator and post-processor,research was done on the effect of air-inlet and air-outlet patterns and battery positions on the electric vehicle aerodynamic performance.The results show as follows：up-outlet mode of wind with one hole has the best aerodynamic performance,and down-outlet mode of wind has the worst aerodynamic performance;with the distance between battery and power cabin increasing,the aerodynamic performance of electric vehicle is improved,and then deteriorated,and the distance of 230 mm fits the best electric vehicle aerodynamic performance.
