摘　　要：借助于计算流体力学软件FLUENT,对一小货车外流场进行了数值计算,求得了压力和速度的分布情况,计算出了风阻系数和升力系数,对其流场进行了分析,并与加装导流罩后做了比较。这种数值计算的方法对于节约成本、缩短研发周期有着一定的参考意义。By using The CFD software FLUENT,the external flow field around a truck body was numerically calculated. Pressure and velocity distribution was got and drag coefficient and lift coefficient was calculated.The flow field was analyzed and compared to that after installed Conducting fluid cover.This numerical calculation method had a reference meaning to reduce costs and research time.
