以顶部开口舱室船舶油池火灾为研究对象,在火灾烟气流动蔓延现象及其相关流动模型的基础上建立溢流烟气点源简化模型对临舱火灾特征参数进行理论分析;在顶部开口舱室火场重构的基础上,对水平开口处烟气流动特性以及临舱内火场特性进行仿真分析,并对其影响因子进行探讨分析,进而为近点源简化模型的适用性进行仿真验证。
The pool fire in ship cabin with a ceiling opening is the main study object in this paper. Based on the fire smoke spreading phenomenon and its relevant model, a simplified point-source model is designed to analyze theoretically characteristic parameters in the ship cabin adjacent to the fire source. The fire scene in a ceiling-opening cabin in reconstructed by Fire Dynamics Simulaltor (FDS). And then the simulation analyses are carried out on characteristics of both the fire smoke at the opening and the fire scene in the adjoing cabin as well as the main influence factors. The applicability of the simplified point-source model is verified by simulation.
