摘要 利用F luen t软件对隧道火灾中火羽流特性进行了模拟分析,研究了隧道坡度对火羽流的影响,与前人所进行的数值模拟进行了比较,为隧道火灾的研究提供了一种有效的研究手段,为进一步研究隧道火灾临界通风速度奠定了基础。 To make numerical analysis of characters of fire plumes in tunnel fires, commercial software Fluent was used. The effects of tunnel slope on fire plumes were showed. By comparing simulation results with previous work done by I. Gasser, an idea that Fluent could be used to tunnel fires research is approved. It is a useful and effective mean to study characters of fire plumes in tunnels. The object of this paper is to prepare for the next step of research of critical ventilation velocity in tunnel fire situation.
