MODEL DEVELOPMENT FOR MULTICOMPONENT MASS-TRANSFER WITH RAPID CHEMICAL-REACTIONS IN A SMALL DROP

Multicomponent mass transfer accompanied by instantaneous chemical rea ctions in a small drop has been modeled and simulated for the case whe re two different solutes diffuse from a continuous phase into the drop and react rapidly with a third reactant in the drop. The computationa l results obtained by Galerkin's finite element method are reported in terms of concentration profiles, the locations of reaction front, the cumulative mass flux, and the enhancement factor. The effects of phys ical parameters, such as diffusivities of the solutes and the reactant , the interfacial concentration of solutes, and the relative amount of the reactant, on the calculated quantities are discussed.
