摘要
针对毛细芯圆管热管内部的耦合流动与传热问题进行模化分析，建立了二维轴对称模型，并进行了数值模拟。与前人一些关于高温钠热管的试验结果比较表明，数值计算结果与试验结果偏差不大，而且它们的变化规律也相符得很好。
A modelling analysis is presented for the inner flow and heat transfer problem of heat pipes,and a joint two dimensional axial symmetrial flow and heat transfer model is established.Based on it,a numerical simulation is conducted.Compared to the existing experimental results in the same conditions,the deviations of the numerical results from the experimental are small,and their varying regulations are very consistent,too.
