防风网对煤堆遮风效果的风洞实验研究

Wind tunnel observation on the effect of a porous fence on shelter of a triangular coal pile

  • 摘要: 为了考察防风网对堆场煤堆的遮风效果,进行了防风网与煤堆之间区域的流场可视化实验.使用风洞模拟大气边界层条件,并将开孔率为38.5%的防风网模型布置在煤堆模型前方.实验中采用粒子成像测速(PIV)系统测量了防风网和堆场区域的平均风速分布,并且获得了煤堆表面的摩擦风速分布,进一步估箅煤堆起尘量的变化情况.实验发现,防风网可有效降低煤堆表面迎风区域的摩擦风速,而对背风面的流场分布影响较小.研究结果可为防风网的遮护作用提供一定的实验支持.
