地铁车站挡烟垂壁对火灾烟气流动的影响分析
Analysis of Subway Station Smoke Screen Effect on Fire Smoke Movement
摘要
Abstract
Using turbulent flow numerical simulation, a number of conditions before and after smoke screen installation in the typical single-island station's public area of Beijing subway were simulated in the fire situation. The numerical simulation work is entirely based on existing actual physical boundaries, and considers the heating from the train and lighting, also from the people and the personnel effects on flow.The temperature and smoke flow situation before and after setting up the smoke screen were analyzed by numerical simulation. The results show that setting up the smoke screen for old island station of Beijing subway is important. It can inhibit the smoke flow and reduce the temperature of evacuation channel. It will greatly improve the safety of the station under fire.关键词
