| 摘 要： | 应用CFD模拟软件Fluent对开孔率为40%的新型防风网前后流场进行了模拟,考察了无导流板和单一角度、交错角度及渐进角度3种形式的导流板对防风网后物料堆表面速度、压力和湍动能变化的影响。模拟结果表明:导流板可使渗流风上扬,减弱了对料堆迎风面的冲击力,改善了抑尘效果;与其他导流板形式相比较,渐进角度式消除了网堆之间速度回流区的影响,具有更好的导流、整流作用,保证了网后流场的稳定性,抑尘效果明显提高。

| Abstract: | Fluent software was used to simulate the wind flow field around a new-type porous fence with a porosity of 0.4 to indicate the changes of velocity,pressure coefficient and turbulence kinetic energy around a triangular prism model located behind the porous fence under different deflector forms.The numerical predictions showed that the deflectors play a guiding role and makes the flow up to a certain angle to reduce the direct influence on the windward of the prism.In addition,it showed that the form of gradu... |
