Type of article: Article

Summary

A THERMOSYPHON WITH R113 AS THE WORKING FLUID EMPLOYING FILL RATIOS BETWEEN 0.02 AND 0.4, IE 2 AND 40% OF THE EVAPORATOR VOLUME, WAS EXPERIMENTALLY AND THEORETICALLY INVESTIGATED. A CRITICAL HEAT FLUX (FOR WHICH DRY-OUT OCCURS) WAS MEASURED WHICH INCREASES FROM ABOUT 10 KILOW/M2 AT 5% FILL RATIO TO ABOUT 50 KILOW/M2 AT 40% FILL RATIO. THE THEORETICAL PREDICTIONS ARE IN CLOSE AGREEMENT WITH THE EXPERIMENTAL RESULTS.
