摘要:

为寻找储罐池火灾救援中的最佳灭火位置,选择最优化的应急演练方案,通过Mudan模型,分析池火灾燃烧特性,计算大型池火灾不同条件下的热辐射范围和强度;以某化工园区的真实储罐数据建立三维仿真模型,完成池火灾燃烧过程中动态热辐射演化三维仿真效果。结果表明:在有风条件下,火焰会朝下风向偏移,火灾热辐射危害范围也会受到风力影响,对于上风向区域,火灾热辐射危害范围受到风力影响减小;对于下风向区域,火灾热辐射危害范围受到风力影响增大。

Abstract:

In order to find the best fire extinguishing position and make key decision in tank fire rescue, this article analyzed the combustion characteristics of tank fire by the Mudan model, and calculated the thermal radiation range and intensity under different conditions of a large pool fire. A three-dimensional simulation model was established based on the real tank data of a chemical industry park, and the three-dimensional simulation effect of dynamic thermal radiation evolution in the combustion process of pool fire was realized. The results show that, in windy conditions, the flame will shift downwind, and the thermal radiation damage range of the fire will also be affected by the wind. For the upwind area, the thermal radiation damage range of the fire will be reduced. For the downwind area, the thermal radiation damage range of fire is increased due to the influence of wind.
