| 摘 要： | 锂/亚硫酰氯电池的发热问题会影响水下航行器电池舱段的工作效率，并可能导致严重的安全事故。采用流固耦合传热的方法，建立了某型水下航行器电池舱段内部热过程的数学物理模型，利用FLUENT 6.2软件仿真计算了其工作时内部温度分布情况和温度随时间的变化关系，并对某一工作条件下温度分布和温度随时间的变化关系进行了试验验证。结果显示:水下航行器电池舱段内部温度分布和温度随时间的变化关系主要和单体锂/亚硫酰氯电池的放电电流和传热介质的导热率有关。

| Abstract: | Exothermic question of lithium/thionyl chloride battery will affect the efficiency of battery compartment of underwater vehicle,and may cause serious safety problems.Thus,the thermal process in battery compartment is analyzed by using CFD.Its mathematical and physical models are established by using coupled fluid-solid heat transfer method,and the temperature contours and temperature-time curves are simulated by adopting FLUENT 6.2 software.Also,they are tested experimentally.The test results indicate that the temperature contours and temperature-time curves inside the battery compartment are mainly relevant to the discharging current of ER48660 lithium/thionyl chloride battery and the heat conductivity of media. |
