摘要/Abstract

摘要： 以某全尺度船舱火灾试验为基础，依据能量守恒定律定量分析了不同通风条件下火灾过程中舱壁升温、以辐射及对流方式向周围舱室传热、高温烟气传热等方式进行热量扩散的比重关系。结果表明，在该试验条件下,高温烟气扩散和舱壁升温占据主要部分，而经舱壁向相邻舱室扩散的热量最大不到10%。

Abstract: Based on a full-scale cabin fire test , according to the law of energy conservation, this paper quantitatively analyzes the specific gravity relationship of heat diffusion in the process of fire under different ventilation conditions, such as bulkhead temperature rise, heat transfer to surrounding compartments by radiation and convection, and heat transfer of high-temperature flue gas. The results show that under this test condition, the high-temperature flue gas diffusion and bulkhead temperature rise occupy the main part, while the maximum heat diffusion from the bulkhead to the adjacent compartment is less than 10%.
