摘　　要：为提高水面舰船消防预案的有效性,针对制定舰船消防预案的需求,设计了具有工程实用性的数值模拟方案,并以某一主机舱所处防火主竖区为典型案例,采用火灾动力学场模拟方法,模拟起火舱室及相邻舱室采取灭火措施后的舱内烟气温度、舱壁和顶壁温度、CO气体浓度、能见度等参数随时间的变化,并分析火灾对扑救人员的威胁以及灭火措施对火灾控制的影响。实例计算表明,及早发现初火并正确操作至关重要,没有控制住且进一步发展的火灾,机械通风状态对舱内火灾早期烟气运动的影响较大,舱壁喷水冷却对降低舱壁温度效果明显,但封舱灭火后需要较长时间才能达到安全状态等。数值模拟结果对进一步细化消防预案具有重要意义。In order to raise the feasibility of predetermined fire-fighting plans, someplans were designed and calculated with field-simulation numerical model. Taking a vertical fire zone with a machinery cabin as a typical example, the program of the simulation were designed first, then the main factors of the on-fire cabin and adjacent cabins were calculated. The effects of the fire-fighting plans on fire-fighting were analysed. The simulation results could be significantly meaningful for establishing fire-fighting plans.
