| Abstract: | With the use of SST model of the finite-element computational fluid dynamics software ANSYS CFX,the paper performs the numerical simulation on aerodynamic drag of the van body truck,and computes the aerodynamic drag,studies the pressure distributing of the body,then the result is compared with the experimental data to verify the accuracy of numerical simulation.Through Analysis of the surface pressure contour plots and flow lineshape,which provides basic reference for the reduction of van body truck aerodynamic drag. |
