Propagation of a Self-Sustaining Evaporation Front in Freon Mixtures

Abstract

Presented are results of studying the dynamics of evaporation front propagation in mixtures of R21/R114 freons with the concentration of volatile component R114 in the range of 0–0.22 under saturation, as well as at subcooling to 20 K. The dependence of the front velocity on the temperature difference with a stepwise heat release is obtained; spectral analysis of oscillation characteristics of the evaporation front interfacial boundary is performed. It is shown that the difference in the dynamics of the evaporation front in these experiments depends on the development of instability at the interfacial boundary of the front.
