Based on the studies of the Standard, RNG models and SST model, a vehicle external flow field is calculated with three different models. Calculation results are compared with that of experiment. It is found that the error between the simulation results of the drag coefficient of RNS model and the wind tunnel experimental results are minimal. In the near wall region and airflow separation simulations, the simulation results of SST model are more close to the actual condition compared with standard and RNG models.
