将数值模拟中的大涡模拟方法应用于某汽车配件城仓库火灾场景重构,对火灾原因和过程进行分析。根据现场人员证词和燃烧现场取证,对火灾的发生进行场景重构模拟,确定火灾是由电气短路造成。将模拟结果中关键部位的温度、有毒气体和烟气浓度等数据与火灾现场专家勘察结果对比,排除了人为纵火的可能性。采用并行运算方法,较好的预测了火灾发展和有毒烟气的运动。为实际火灾场景的调查提供了数值模拟的科学方法。
The large eddy simulation method in numerical simulation is applied to reconstruct the scene of warehouse fire in an auto parts city, and the cause and process of fire are analyzed. According to testimony on site and evidence collection on the scene of the fire, a scene reconstruction simulation of the occurrence of the fire confirmed that the fire was caused by the electrical short circuit. The simulation results of the key parts of the temperature, toxic gases and flue gas concentrations and other data with the fire site experts survey results, excluding the possibility of artificial arson. The use of parallel computing methods, a better prediction of the fire development and toxic fumes movement. A scientific method of numerical simulation is provided for the investigation of the actual fire scene.
