摘　　要：为探究双开口舱室火灾的温度场特性,选取典型双开口舱室作为研究对象,利用火灾动力学模拟软件(FDS)构建火灾场景,模拟不同火源功率下的火灾发展过程,并分析舱室内部温度场分布规律。结果表明,在整个双开口舱室火灾发展过程中,在气流的影响下火焰呈振荡状态但总体上不会发生明显的倾斜;双开口舱室内水平高度越高,整个水平面的温度越趋向于一致,火源功率越高趋势越明显;在一定可接受误差水平下,双开口舱室火灾羽流中心线的温度分布在趋势上仍然符合McCaffrey模型。In order to explore the temperature field characteristics of double-open cabin fire,taking a typical double-open cabin as the research object,the fire dynamics simulation software(FDS)was used to construct a fire scene,so as to simulate the fire development process under different fire power sources and analyze the temperature field distribution law inside the cabin.The results showed that the flame oscillates under the influence of airflow but does not tilt significantly in the whole process of fire development in the double-opening chamber.The higher the horizontal height in the double-open chamber,the more the temperature of the whole horizontal plane tends to be consistent,and the higher the power of the fire source is,the more obvious the trend is.Under certain acceptable error level,the temperature distribution of the center line of the fire plume in the double-opening chamber still conforms to the McCaffrey model.
