Abstract
We consider a wellknown diffuse interface model for the study of the evolution of an incompressible binary fluid flow in a two or threedimensional bounded domain This model consists of a system of two evolution equations namely the incompressible NavierStokes equations for the average fluid velocity u coupled with a convective Cahn–Hilliard equation for an order parameter phi The novelty is that the system is endowed with boundary conditions which account for a moving contact line slip velocity The existence of a suitable global energy solution is proven and the convergence of any such solution to a single equilibrium is also establishedM Grasselli is a member of the Gruppo Nazionale per l’Analisi Matematica la Probabilità e le loro Applicazioni GNAMPA of the Istituto Nazionale di Alta Matematica INdAM We also wish to acknowledge the reviewer whose comments and important remarks have improved the initial version of the article We thank Hao Wu for pointing out a gap in a previous proof of Theorem 33
