地铁区间隧道火灾情况下的烟气扩散研究
Study on Smoke Propagation in Subway Tunnel with a Fire Scenario
摘要
Abstract
Aiming at the technical difficulties of smoke propagation in subway tunnel with a fire scenario, we conducted the fire simulation of a section tunnel of Zhengzhou Metro Line 1 by using CFD software STAR-CCM.The critical wind speed of one-way diffusion of smoke is not less than 2.0 m/s when fire intensity is 7.5 MW.It is concluded from the simulation analysis that people escaped downstream should try to lower their height and go along the middle line of the tunnel.The gas flow condition measured by field experiment was compared with the numerical simulation results under the same condition.The results show that the numerical simulation method is reliable.The research results provide important reference for studying the flow of smoke and making evacuation plans.关键词
