某酒楼采用窗槛墙替代防火挑檐的可行性探讨

Feasibility of the windowsill wall instead of fire canopy in a restaurant

以某酒楼建筑为研究对象,采用FDS数值模拟,对其内部火灾及烟气流动蔓延规律进行研究,主要分析窗槛墙、防火挑檐、风速对烟气运动的影响以及窗户开口处的热辐射通量和温度变化,为该酒楼拟采用一定高度的窗槛墙替代防火挑檐的做法提供数据支持和理论依据。

Based on the FDS simulation, the flow and spread rule of the fire and smoke in a hotel were studied in this paper. The influence of the windowsill wall, fire canopy and wind velocity on the smoke move, the change of thermal radiation flux and temperature were mainly analysed in order to offer theory evidence for the windowsill wall instead of fire canopy in a hotel.
