1.
In this paper,an experimental study on fluctuation characteristics of wind speed within blowing sand flow over the Nylon checkerboard sand barriers with different porosities in wind tunnel in carried out.
通过对不同孔隙度格状沙障内风沙流中风速波动特征研究发现:风沙流中各高度层风速波动具有很好的相关性,其波动幅度随孔隙度的增加而减小;瞬时风速在时间序列上波动的均一性随不同高度间距离增加呈递减趋势;瞬时风速的波动性一方面受下垫面性质及外在环境条件的影响,另一方面与其所在高度层沙粒数量和运动状态有关。
