Abstract

The characteristics of the boiling heat transfer for a concentric-tube open thermosyphon are examined in detail. Fluorocarbon R-11 refrigerant as a testing fluid is utilized. Out of a number of possible controlling variables, the effects of the heat flux, the void ratio, and the diametric ratio of the concentric-tube on the heat-transfer performance are determined. From the present experimental results it is demonstrated that total heat flux can be appropriately predicted by a superposition of the heat flux due to the available correlations for free convection and due to the correlations experimentally determined for boiling heat flux.
