Abstract:
In the talk we shall present the last results on some diffuse-interface models for flow and phase separation of binary fluids which are based on the coupling of the Navier-Stokes equations with the nonlocal Cahn-Hilliard equation. The nonlocal Cahn-Hilliard/Navier-Stokes system has been studied analytically in a series of papers (cf. \cite{CFG,FG1,FG2,FGK,FGR,FGG,FRS}). The attention will be focused on the more recent results concerning the case where the two densities are different (weak solutions, cf.\cite{F}), where the mobility is degenerate and the potential is singular (regularity and optimal control, cf. \cite{FGGS} and \cite{FGS}), and where the two-phase fluid is non-Newtonian (weak solutions and uniqueness, cf. \cite{FGP}). %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% \begin{thebibliography}{11} \bibitem{CFG} P.
