Abstract

Experimental data were obtained of the post-burnout heat transfer to Freon 22 flowing upward in a vertical, uniformly heated rounded tube at high subcritical pressures over a range of reduced pressure from 0. 68 to 0. 84. Based on an assumed model, the actual quality was estimated from the heat transfer data. The distinctive characteristics of the difference between the vapor mass fraction in thermodynamic equilibrium state and the actual quality were found in low and high equilibrium quality region respectively. Dimensional correlations of this difference were tentatively obtained.
