船舶密闭舱室火灾过程及其模拟计算

Ship sealed cabin fire process and its numerical simulation

密闭舱室火灾是一个三维非定常过程，压力升高是这一过程的重要特征。本文采用质量守恒的方法进行压力校正，建立了计算密闭舱室火灾过程的数学物理模型，数值计算采用非均匀交错网格，结果与实验和理论分析相符较好。

\ Sealed cabin fire is a 3 D and unstable process. The pressure arising is an important property of the process. This paper calculated the pressure during the sealed cabin fire, and modeled the process of sealed cabin fire. A numerical simulation of the sealed cabin fire has been done using field model. The results are in keeping with the experiment study.
