Abstract
Experimental studies of the effect of adjacent solid spheres with arbitrary arrangement on the rates of evaporation of a drop were carried out for water and octane drops into dry air, for RePA = 72–234, Sc = 0.59–1.61, diameter ratios Dp/DA = 0.57–0.89, dimensionless distance between centers of drop and solid sphere, L/DA = 1. 12–9.44, and dimensionless distance between center axes of drop and solid sphere, W/DA = 0–3.63.
New correlations for the effect of solid spheres on the rates of evaporation were proposed. By use of these correlations, a prediction of void function, which relates mass transfer rates of a group of drops or particles to that of a single drop or particle, was made.
