Summary

A survey is given on condensation heat transfer inside a two-phase thermosyphon including a detailed description of fluid flow as well as a review of published experimental and theoretical investigations. A total of 2889 data points derived from 18 research works has been evaluated covering wide ranges of thermal and geometrical parameters: 10 different working fluids, saturation temperature (14 to 340 deg C), pressure (4 to 3.950 kilopascals), inside tube diameter (14 to 66 mm), length of cooling zone (102 to 2450 mm), and inclination angle (0 to 85 deg). Correlations are proposed for condensation heat transfer inside a two-phase thermosyphon. Remaining deviations are due to effects of shear stress at the liquid-vapour interface, effects of non-condensable gases and effects of a partial flooding of the cooling zone in the case of superfilling the thermosyphon.
