We discuss the sharp interface limit of a diffuse interface model for a two-phase flow of two partly miscible viscous Newtonian fluids of different densities, when a certain parameter ϵ>0 related to the interface thickness tends to zero. In the case that the mobility stays positive or tends to zero slower than linearly in ϵ we will prove that weak solutions tend to varifold solutions of a ...
