采用场模型和贴体坐标技术对某机场候机大厅的烟气填充情况进行了研究。研究结果表明 ,烟气下降到对人逃生有害的高度需要相当长的时间 ,随着火源强度的增加 ,顶棚射流速度和烟气温度增加 ,烟气层底面高度下降
The field model and body coordinate technique were used to study the flue gas filling in an airport waiting hall. The results show that it takes quite a long time for flue gas to descend to a height that is harmful to human escape. As the intensity of fire source increases, the ceiling jet velocity and flue gas temperature increase, and the height of the flue gas layer bottom surface decreases
