防风抑尘网数值模拟及设置方案分析

The Analysis for Setting Scheme and Numerical Simulation of Wind Dust-Controlling Net

针对神华内蒙古准能矸电二期工程煤堆场设置防风抑尘网的问题,利用Fluent软件建模,对迎风向单面设网和四周设网的防风抑尘效果进行三维数值模拟和分析.结果表明,采用单面设网能基本满足防风抑尘的需要,其最佳几何尺寸为,网的长度和高度分别为105m和20m,网的开孔率为40%.当来流风速约为5m/s时,单面防风抑尘网对风速能起到明显的消减作用.

For the problem of setting wind dust-controlling nets around the Coal yard of Shenhua Zhungeer,Inner Mongolia coal and gangue power phase II project, by using Fluent software modeling, making 3-d numerical simulation and analysis for the effect of single network and around the wind dust- controlling on the windward. The results show that the single set can basically meet the wind dust-control- ling needs,the best geometry size is that length and height of 105 m and 20 m respectively,opening rate of 40%,when the wind speed is about 5 m/s, the single side wind dust-controlling nets can have obvious reduction effect of wind speed.
