摘要
应用RNGk-ε湍流模型对国产某型号轿车车身进行了外围流场数值模拟,针对高速条件下轿车尾部升力随之增加、操纵稳定性下降的特点,设计了一阶和二阶尾翼。仿真结果表明,增加尾翼后,轿车尾部的升力明显降低,从而提高了轿车高速行驶条件下的操纵稳定性。研究结果为轿车车身设计和轿车改装提供了理论支持。
By using RNG κ-ε turbulence model, a numerical simulation on peripheral flowfield of an automobile is performed. In order to increase manipulation stability, a rear wing is appended to an automobile. The simulation result shows that the rear elevating force reduces dramatically after the appending of rear wing, which supports the design of automobile body and automobile refitting.
