大门空气幕沿门宽方向阻隔特性分析

摘要

基于不可压缩流体 N-S 方程及 k-ε两方程湍流模型，采用有限体积法，对铁路车站大门空气幕的阻隔特性进行了数值计算研究，分析了沿大门宽度方向上的空气流通量，并通过对比无空气幕时计算结果，分析了空气幕的单位门宽方向空气幕的阻隔效率。%　　In this paper, it was simulated based on equation N-S and two equation k-ε turbulence models, with the finite volume method, that is the obstructive efficiency of air curtain along the width of gate in a Railway station. Air flux and the obstructive efficiency of air curtain along the gate width were analyzed, compared with the simulation result without air curtain.
