中庭火灾烟气流动的大涡模拟
Large eddy simulation of smoke movement in atrium fire
摘要：
采用大涡模拟的方法，对中庭火灾烟气的流动过程进行了模拟，了解了中庭烟气的蔓延过程，得到了烟气的速度场和温度场、顶棚射流的速度和温度的详细结果。模拟结果表明，大涡模拟能比较准确地预测中庭内烟气的流动状态，可用于指导中庭建筑的防火设计。

Abstract：
Simulates the smoke movement in atrium fire by using large eddy simulation. Obtains some details of the smoke spreading, the smoke velocity filed and temperature field, and the ceiling jet velocity and temperature. The results indicate that large eddy simulation can accurately predict smoke movement, and be used as a reference for the fire protection design of buildings with atria.
