铁路分岔隧道典型火灾条件下射流风机选型计算研究

该研究提出针对铁路列车火灾在分岔隧道段的排烟分区划分方法,并进行相应的风机匹配计算。通过PyroSim软件进行数值模拟,对火灾在分岔位置上下游的不同位置进行相应的烟气通风控制,验证排烟分区划分方法的可行性。研究结果对于复杂铁路分岔隧道部位通风排烟系统的设计具有实际的参考价值。

This study proposes a smoke exhaust zoning method for railway train fires in bifurcation tunnel sections and conducts corresponding fan matching calculations.Through the numerical simulation of the PyroSim software,the corresponding smoke ventilation control is carried out at different positions of the upstream and downstream of the bifurcation position,and the feasibility of the smoke exhaust partition method is verified.The research results have practical reference value for the design of ventilation and smoke exhaust system at bifurcations of complex railway tunnels.
