MULTIMODELS FOR INCOMPRESSIBLE FLOWS: ITERATIVE SOLUTIONS FOR THE NAVIER-STOKES/OSEEN COUPLING

In a recent paper (4) we have proposed and analysed a suitable mathematical model which describes the coupling of the Navier-Stokes with the Oseen equations. In this paper we propose a numerical solution of the coupled problem by subdomain splitting. After a preliminary analysis, we prove a convergence result for an iterative algorithm that alternates the solution of the Navier-Stokes problem to the one of the Oseen problem.
