摘　　要：针对船舶火灾发展过程中对周围舱室温度场影响问题,基于CFD技术对船舶火灾热流场进行仿真。以船舶火灾舱室和邻舱为对象,仿真分析不同火灾场景热流场的分布及相邻舱室、共用壁面温度随时间变化规律;探讨不同火灾规模、不同火灾舱室尺度、舱壁厚度等对共用舱壁平衡温度、邻舱气体平衡温度和达到平衡温度所需时间的影响。仿真结果显示,共用舱壁和邻舱气体所达到的平衡温度和达到平衡温度所需要的时间,主要由火灾规模和火灾舱室长度决定,受相邻舱室尺寸的影响较小;火灾舱室宽度对共用舱壁的平衡温度影响较大,对邻舱气体的平衡温度影响较小。In response to the impact of ship fires on the temperature field of surrounding cabins during the development process,CFD technology was used to simulate the heat flow field of ship fires.Taking ship fire compartments and adjacent compartments as objects,the distribution of heat flow fields in different fire scenarios were simulated and analyzed,as well as the temporal variation of temperature in adjacent compartments and shared walls.The effects of different fire scales,cabin sizes,and cabin wall thicknesses upon the equilibrium temperature of shared cabin walls,adjacent cabin gas equilibrium temperatures,and the time required to reach equilibrium temperatures were explored.The simulation results showed that the equilibrium temperature and time required to reach the equilibrium temperature of shared cabin walls and adjacent cabin gases are mainly determined by the size of the fire and the length of the fire compartment,and are less affected by the size of adjacent compartments;The width of the fire compartment has a significant impact on the equilibrium temperature of the shared cabin wall,but has a relatively small impact on the equilibrium temperature of adjacent cabin gases.
