Analysis and extension of the theory of multicomponent fluid diffusion

Recently we have presented an extended theory for molecular mass transport (Kerkhof and Geboers, 2005). We have indicated the possibility, and the need, to define a new framework for studying and teaching the theory of multicomponent molecular transport in fluids (Kerkhof and Geboers, 2004). Here a new, structured, overview of the subject is presented. An analysis is given of complicated issues in textbooks and review papers
