摘要
Macroscale interfacial conservation equations are derived for transport processes occurring in immiscible fluid-fluid systems possessing moving and deforming interfaces via a rigorous matched asymptotic expansion scheme from the more exact, continuous ('diffuse') microscale equations underlying them. A surface-fixed coordinate system is developed for the parameterization of the interface, alleviating approximations which result when either a material or a space-fixed control volume is used to investigate systems undergoing interphase mass transfer.
