Mass transport from a spherical body into a multicomponent fluid stream

Abstract

This paper analyses mass transfer from a spherical body, either liquid or porous solid, to an n-component fluid stream in uniform flow around the body. The steady-state mass transport rates are calculated from the Maxwell-Stefan diffusion equations (for non-ideal liquid mixtures, in their generalized form) using a matrix method of solution. Proper account is taken of the diffusional interactions between species transfers. The corresponding thermal transport phenomena is also considered in the analysis, which should find application in droplet evaporation, drying, catalytic reaction etc.
