Abstract

Measurements were made of the effect of interaction between two drops on the simultaneous evaporation of two coaxially arranged water and hexane drops for RePA = 64–230, Sc = 0.59–1.57, DB/DA = 0.54–1.58, L/DA = 0.98–11.04 and BM = 0.02–0.64.
The observed diffusion fluxes for water drops were compared with the previous numerical solutions. A systematic deviation from the previous numerical solution under low mass flux conditions was observed for hexane drops. New correlations for the diffusion fluxes of two adjacent drops were proposed by considering the effect of the interaction between two drops, of high mass flux and of variable properties.
