The external flow field dynamic calculation of a heavy duty vehicle is carried with PowerFlow CFD based on LBN method, and the effect of front spoiler design on the drag coefficient and dust removal effect near the door handle position is analyzed. The final improvement scheme is presented based on CFD analysis. The results indicate that improved design of the spoiler decreases the drag coefficient by 2.4 % compared with that of the original vehicle, and dust removal effect is also improved significantly.
