摘　　要：为深入研究鱼雷闭式循环热动力系统壳体冷凝器的传热特性,建立了壳体冷凝器一维传热数学模型。通过仿真计算,获得了壳体冷凝器沿轴向温度、压力以及干度分布特性,讨论了不同冷却通道截面尺寸、入口乏汽质量流量及入口乏汽温度条件对壳体冷凝器工作特性的影响。计算分析结果表明,在壳体冷凝器相同入口乏汽参数条件下,对于不同截面尺寸的冷却通道,其换热特性也不同。壳体冷凝器出口温度受入口乏汽温度影响较大,出口压力受入口乏汽质量流量影响较大。可为鱼雷壳体冷凝器的性能预示和结构设计提供参考。To understand heat transfer characteristic in shell condenser of closed-loop thermal propulsion system of a torpedo, a one-dimensional heat exchange model of the shell condenser is built. And the temperature, pressure and dry- ness distributions along the axis of the shell condenser are acquired with the model. In addition, the influences of three factors on the performance of the shell condenser are discussed. These factors are the cross-section size of cooling channel, the mass flow rate and the temperature of inlet steam exhaust. Simulation results indicate that, for same con- denser inlet steam exhaust, heat exchange of the cooling channel is affected by its cross-section area. The outlet temper- ature of the condenser significantly depends on the inlet steam exhaust temperature, and the outlet pressure mainly de- pends on the mass flow rate of inlet steam exfiaust. This study may provide a reference for performance prediction and structure design of torpedo shell condensers.
