池火灾热辐射量化模型对比分析研究

Research on the Comparison and Analysis of Pool Fire Thermal Radiation Quantitative Model

开放环境中池火灾持续时间久,其主要危害是热辐射。池火灾热辐射计算模型主要有点源模型、Shokri-Beyler模型和Mudan模型等。运用Matlab模拟了池火直径和风速对3种模型热通量的影响,以及3种模型热通量随距离的变化趋势,比较研究了有风和无风情况下3种模型热辐射的传播规律,为定量评价池火灾热辐射后果提供参考。

Pool fire is lasts long in open area and the major hazard is thermal radiation .Pool fire radiation calculation mod-els include point source model ,Shokri-Beyler ,Mudan model and so on .The influences of pool diameter and wind speed on heat flux are simulated ,as well as the changing tendency of heat flux of the three models with the change of distance . The spreading laws of thermal radiation of all three models under or without wind respectively are compared and studied , providing references for the quantitative evaluation of pool fires heat radiation damage .
