| 摘 要： | 为分析鱼雷发射失效后Al/AgO电池在发射管中的热安全性，基于计算流体力学方法，应用计算流体力学软件FLUENT，对鱼雷发射失效后Al/AgO一次电池激活情况下管内强制对流耦合传热进行了数值模拟。考虑了电解液与鱼雷壳体、鱼雷壳体与发射管内海水的对流耦合换热，得到了电解液的温度变化规律以及鱼雷壳体和发射管体上的温度分布规律。仿真结果表明，电池内温度随时间的变化逐渐升高，其最高温度可达107．5℃。

| Abstract: | To analyze the thermal safety of Al/AgO battery in torpedo tube after launching failure, numerical simulation of the conjugate forced convection heat transfer was conducted in the condition of launch failure and battery activation by using the computational fluid dynamics （CFD） software FLUENT. Taking into account the conjugate heat transfer between electrolyte and torpedo shell as well as between torpedo shell and sea water inside the tube, the time histories of the electrolyte temperature and the temperature contour on torpedo shell and tube were obtained. Simulation results show that the temperature in the battery becomes higher with time, and the maximum temperature is 107.5 ℃. |
