Critical heat flux in a closed two-phase thermosyphon

Abstract

A closed two-phase thermosyphon experimental setup with the possibility of recording the coolant and its vapors temperatures was developed. We proved the use of the V. M. Borishansky and S. S. Kutateladze correlations for the determination of the critical heat flux in closed two-phase thermosyphons with the ratio of their internal diameter to the length of the heat supply zone in the range of 1 < dBhym / Lu < 2.
