微型面包车的流场特征及数值计算要点

Structure and numerical simulation of airflow around small van

微型面包车与其它客车有明显差异 ,因此其周围流场就有着不同的特征。以风洞试验数据为参考 ,对长安某微型面包车进行了外流场数值模拟 。

The small van has itself feature in the airflow because of the shape being quite different from other type of passenger cars. Therefore in this paper numerical simulation of airflow around a certain small van is done with reference to the wind tunnel test data. As a result the regular under standings are obtained both in the flow structure and the simulation of this kind of car.
