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 volume method, that is the obstructive efficiency of air curtain along and two equation the width of gate k-ε turbulence models, with the finite 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.
