【摘要】 利用FDS对一起商住合用房火灾事故进行火灾数值模拟重构,通过模拟得出不同热释放速率增长速率下高斯热通量、辐射热通量等参数和烧损情况,与实际火灾场景烟熏痕迹和烧损情况进行对比,证明数值模拟的合理性,对起火点处引起火灾的起火物的燃烧特性进行更好的调查分析。并且通过模拟不同热释放增长速率下氧气浓度、二氧化碳和一氧化碳的变化,对人员死亡原因进行分析。更多还原

【Abstract】 FDS was used to simulate a fire accident that happened in an residential and commercial building,the combustion characteristics including Gauss heat flux,radiation heat flux and burning loss under different fire growth rate conditions were compared to the real fire scenario to verify the rationality of the numerical simulation,and the combustion characteristics of the fire point were analyzed better.The cause of death was analyzed by means of simulating the concentration variation of the oxygen,carbon dioxide and carbon monoxide.更多还原
