Abstract
A fully coupled method for the solution of incompressible Navier-Stoke s equations is investigated here. It uses a fully implicit time discre tization of momentum equations, the standard linearization of convecti ve terms, a cell-centred colocated grid approach and a block-nanodiago nal structure of the matrix of nodal unknowns. The Method is specific in the interpolation used for the flux reconstruction problem, in the basis iterative method for the fully coupled system and in the acceler ation means that control the global efficiency of the procedure. The p erformance of the method is discussed using lid-driven cavity problems , both for two and three-dimensional geometries, for steady and unstea dy flows.
