建筑开口流量系数及其对火灾烟流的影响

在高层建筑火灾试验塔上测试了典型门、窗不同开度时的流量系数。该系数可用于火灾烟气流动预测计算，也可用于压送风量及一般建筑通风换气计算。同时，运用建筑物火灾烟气流动性状预测计算软件，分析了门窗开度及流量的系数对火灾烟流的影响。

Opening Flow Coefficient and its Effect on Fire Smoke Flow

The flow coefficient of the typical doors and windows in different states between opening and closing was tested in a high rise experimental fire tower. It can be used for the prediction calculation of the fire smoke flow and the calculation of the positive air supply as well as for the ventilation. Using the prediction software of the fire smoke flow properties in the building, the effect of the flow coefficient on the fire smoke flow was also studied.
