本文对带保护段的圆管式稳态传热性能测试装置进行了传热分析。计算了多种情况下,径向热流与理想的一维均匀热流之间的偏差。同时对端盘内是否敷设加热器作了分析比较。在此基础上又对该装置的稳定时间作了分析计算。所得结论,对研制、评价及合理使用圆管式稳态传热性能测试装置有一定的指导意义。
In this paper, the heat transfer analysis of a tube-shaped steady-state heat transfer performance test device with a protective section was carried out. The deviation between the radial heat flow and the ideal one-dimensional uniform heat flow is calculated in many cases. At the same time whether the laying of heaters in the end plate for analysis and comparison. On this basis, the stability of the device was analyzed and calculated. The conclusions obtained are of guiding significance for the research, evaluation and rational use of the tubular steady-state heat transfer performance testing device.
