Sinopsis

The effect of droplet size distribution on the rate of evaporation from a cryogenic liquid sprayed over a horizontal surface is investigated. Starting from existing theory theoretical dimensionless correlations are derived for the active heat transfer area and the heat transfer coefficient in film boiling of sprays with nonuniform initial size distributions. It is thus shown that, for all practical purposes, the Sauter mean diameter is the only parameter that is needed to describe statistically a spray of a liquid undergoing film boiling. The correlations obtained are then checked against the experimental data available in literature and the theoretical results are found to be reliable.
