横向舱壁对火羽流作用的临界高度分析

摘要

分析舱室横向壁面对轴对称火羽流作用的理论临界高度,将舱室内油料火灾的羽流运动速度和质量卷吸量仿真计算结果与Zukoski,McCaffrey,Thomas-Hinkley及Heskestad经验羽流模型进行比较,给出较为合理的羽流模型,仿真计算结果验证了理论分析的正确性.%The critical height of axial symmetrically fire plume effected by transverse cabin wall was theatrically analyzed.The oil fire plume kinetic velocity and mass flux in cabin calculated by experienced plume model Zukoski,McCaffrey,Thomas-Hinkley and Heskestad were contrasted with simulated results,and the relatively rational fire plume model was obtained.Meanwhile,the simulated results agrees well with the theatrically analyzed conclusion.
