【摘要】 本文对竖直两相闭式热虹吸管内的凝结换热进行了理论分析和实验研究。理论分析中考虑了两类不同的界面切应力的影响和饱和压力的影响。在不同充液量和不同压力下进行了实验,实验结果在一定的温差范围内与理论分析值符合较好。更多还原

【Abstract】 This paper presents a theoretical analysis and experimental results of condensation heat transfer in the vertical two-phase closed thermosyphon. The effects of the relative importance of the two kinds of shear stresses and the effects of the pressure are considered in the theoretical prediction. The experiments are carried out at different filling ratios and pressures. The theoretical calculations agree with the experimental results in a certain range of temperature differences.更多还原
