ABSTRACT

In this paper we present an Augmented Lagrangian Method to solve the Navier-Stokes equations for a Bingham fluid flow. We describe two algorithms for the solution of the resulting discrete system: Uzawa and Newton-GMRES techniques. A comparison of these two methods on the test case of the driven lid cavity shows that the Uzawa method seems to be more efficient than the other one.
