| 摘 要： | 应用FLUENT软件,分别对汽车造型的不同处理方法、发动机安放位置、离地间隙、发动机舱冷却风的排出模式进行气动性能仿真.结果表明:汽车造型的处理方法中以加车轮对气动性能影响最大,发动机存在最佳的安放位置,不同的离地间隙对仿真结果影响很大,选择发动机舱冷却风的排出模式要综合考虑阻力系数和升力系数.

| Abstract: | Analyzed the aerodynamic characteristics through simulation of different treatment methods of car modeling,placement of engine,ground clearance and the removal mode of the cooling air in engine cabin with FLUENT software.The results show that: adding the wheels has the greatest impact on the aerodynamic characteristics,there is a best place for engine,and different ground clearances have great impact on the result of simulation.So,selecting the removal mode of the cooling air in engine cabin has to consider... |
