稳压器在船用核反应堆舱室散热的模拟研究

Simulation of Heat Transfer of Pressurizer in Ship Nuclear Power Plant Cabin

运用CFD方法,对稳压器在船用核反应堆舱室的散热进行研究,得到了舱室内温度场的空间分布特征,分析了不同舱室温度、不同船体倾角下的散热情况;结果表明:船体倾角对散热影响不大,但舱室温度对散热影响较大;舱室温度越低,倾角越小,散热量越大。

The heat diffusion phenomenon of Pressurizer in a cabin was studied with the CFD method, get ting the spatial distribution characteristics of the temperature field. The heat diffusion in case of different cabin temperatures and different ship inclination angles was simulated in this work. The results indicated that the effect of ship inclination on the heat diffusion is weak, but the effect of cabin temperature is signif icant. The heat diffusion increases with the cabin temperature decreasing and the inclination angle decrea sing.
