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.

Key words: engineering thermophysics, lithium/thionyl chloride battery, exothermic question, coupled fluid-solid heat transfer, computer simulation
