摘　　要：以成都地区某栋高层住宅建筑为研究对象,应用PyroSim软件对其进行了数值模拟,探究了不同风向对于高层住宅室内火灾烟气流动的影响,结果显示:西南风影响最大,西北风影响最小,南向风比北向风影响大,东向风比西向风影响大。同时提出了一些措施来减弱风向对于室内烟气流动的影响,为成都地区高层住宅消防设计、人员安全疏散提供一定的参考。Taking a high-rise residential building in Chengdu area as the research object,it was numerically simulated by PyroSim software,and the influence of different wind directions on indoor fire smoke flow of high-rise residential buildings was explored.The results showed that the southwest wind had the greatest influence,the northwest wind had the least influence,the south wind had greater influence than the north wind,and the east wind had greater influence than the west wind.At the same time,some measures are put forward to reduce the influence of wind direction on indoor smoke flow,which can provide some reference for fire protection design and safe evacuation of high-rise residential buildings in Chengdu.
