Dry-out model in two-phase flow
Abstract
A two-phase water-steam flow in a heated channel is experimentally studied. The critical flux is calculated by analysis of the evolution of the liquid film under the action of various elementary phenomena (evaporation, entrainment, and redeposition of the droplets) which are observed in experiments. Models are drawn up for calculating the effect of the elementary phenomena. The potential advantages of this modelization are (1) a better understanding of experimental results, and (2) the possibility of obtaining information which will apply outside the zones investigated experimentally or under conditions which are difficult to reproduce.
