摘要
通过给出描述横条栅栏附近风场初边值问题基本方程,成功实现了对栅栏风洞实验结果的数值模拟.在此基础上,给出栅栏背风面的风场分布规律以及栅栏高度、孔隙度和空行数等对栅栏有效防护距离的影响.
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.
