| 摘 要： | 电站挡风抑尘板用于露天的煤场的防风抑尘工程。采用标准k-ε紊流模型结合SIMPLE算法对正、侧阻风面夹角α=150°正六边形孔、α=180°圆孔和α=150°圆孔挡风抑尘板后的流场特性进行了数值研究。结果表明:α=150°、正六边形孔挡风抑尘板后流场稳定,挡风抑尘效果最好。

| Abstract: | The porous wind fences of the power station are used of abating wind erosion and wind-blown dusts.The flow characteristics behind a orifice has been investigated numerically using the standard k-ε turbulence model integrated with the SIMPLE algorithm,and the orifice with the angle of the face and the side α is 150° or 180°,and which hole shape is round or hexagon.The results suggest that the orifice which has the angle α of 150° and hexagon hole has better effects on abating wind erosion and wind-blown dusts than others,and the flow trend to steady. |
