| Abstract: | The complex flow around camion was numerically simulated with the three-dimensional incompressible RANS and the S-A turbulence model in this paper, the pressure distribution, flow characteristics and aerodynamic drag of the camion were obtained. The results show with good precision on small grids amount. Finally, the ways to decrease aerodynamic drag were indicated. |
