Dispersed flow film boiling during reflooding
Abstract
A droplet model was used for the analysis of the fluid flow and heat transfer in the dispersed flow film boiling regime during reflooding of a tubular channel. Comparisons were made of the predicted wall heat fluxes, vapor temperatures, qualities, and droplet diameters and the experimental data. The heat transfer predictions are in agreement with the data at locations away from the quench front for certain values of the initial droplet diameter and velocity. It was observed that the initial droplet diameter, and to lesser extent the initial droplet velocity, had a large effect upon the predicted wall heat flux. Calculations were made for initial droplet sizes varying between 0.5 and 2.0 mm.
