Diffusion and Convection With Chemical Reaction in a Three-Phase System

摘要

The authors present a general theoretical analysis of the diffusion problem including chemical reaction for globules and liquid membrane in a 3-phase system. Volume-averaging transport equations are derived for globules and membrane with chemical reaction in both phases and for the continuous phase with diffusion and convection effects. With these equations, a one-concentration model to double emulsion system (globules and membrane) was derived, and for this the principle of local mass equilibrium was applied.
