摘　　要：采用大涡模拟的方法,对某典型船舶机舱发生火灾后,进、排风机在不同启闭组合的通风条件下烟气控制的综合效果进行对比分析,旨在探究通风设备的开启对船舶火灾发展及烟气控制的综合影响。结果表明,在模拟研究的火灾阶段内,机械进风系统和机械排风系统的开启均能有效降低火场温度、提高火场能见度,对于火灾烟气控制具有积极影响。The large eddy simulation （LES） was performed to analysis the comprehensive influence of smoke control during the engine room fire with different conditions of the supply and exhaust fans. Numerical results showed that both the supply and exhaust ventilation can reduce the temperature as well as improve the visibility of the fire compartment during the fire stages in these simulation, that is to say the mechanical ventilation has good effects on smoke control during ship engine room fire to some extent.
