On an incompressible Navier–Stokes/Cahn–Hilliard system with degenerate mobility
Annales de l'I.H.P. Analyse non linéaire, Tome 30 (2013) no. 6, pp. 1175-1190.

We prove existence of weak solutions for a diffuse interface model for the flow of two viscous incompressible Newtonian fluids in a bounded domain by allowing for a degenerate mobility. The model has been developed by Abels, Garcke and Grün for fluids with different densities and leads to a solenoidal velocity field. It is given by a non-homogeneous Navier–Stokes system with a modified convective term coupled to a Cahn–Hilliard system, such that an energy estimate is fulfilled which follows from the fact that the model is thermodynamically consistent.
