Large eddy simulation of smoke movement in mall

Abstract

用大涡模拟计算了一个没有通风的室内商业街火灾的烟气流动。由于所需的计算时间过长 ,目前仅计算了一个算例 ;介绍了这个算例的一些结果。数值模拟试验证明大涡模拟可以用于大尺度问题的模拟 ,能够表明烟气流动的细节。 Smoke movement during fire in a mall without venting was simulated by large eddy simulation (LES) model. Due to the huge computational time needed, only one case was simulated and presented. The numerical simulation results indicate that LES can be used to large-scale geometry and can show the smoke movement in details. More studies are needed to get a complete figure of the smoke movement.
