摘　　要： 以油池及甲板污油为火源点,基于FDS软件平台采用大涡模拟方法对某双机双桨船舶机舱火灾的发生、发展全过程进行了数值模拟。研究了该船舶机舱火灾发生及发展过程中不同时刻和不同高度下烟气运动与火焰蔓延的变化规律、舱内温度场的分布等情况以及它们之间存在的关系。对该双机双桨船舶机舱及类似结构的其他机舱的防火设计、火灾监测及防火策略提供了重要参考。 The pool fire and the deck＇s waste oil were used as several fire sources in this paper, to simulate the occurrence and the development process of fire in a certain ship engineroom under the condition of the ventilating based on the software platform of FDS and used the method of large eddy simulation. The law of smoke movement and flame spread, the distribution of the temperature field in different time and different height, also the relationship between them in the process of the ship engine-room fire were studied. It provided some references to the fireproofing design, fire monitoring and fireproofing strategy of the ship engine-room.

关 键 词： 船舶机舱 火灾 大涡模拟 火焰传播 数值模拟
