Abstract:In this paper, we provided the basic equation of the question of the beginning of wind field value near the horizontal bar and succeeded in realizing the numerical simulation to the bar wind-tunnel experimental result. On this basis, we provided the distributed law of the leeward wind field of the bar and drew the conclusion that there is the influence from the height of sand fence, the degree of open hole and the number of blank lines.
Keywords:sand fence   flow field distributing   wind tunnel experiment   numerical simulation
