Abstract
Abstract In this paper, we develop a numerical method for solving two dimensional viscous flow problems in the presence of obstacles in unsteady regime. In fact, the present study is based on a Chorin type Projection method [1] of first order in time and second order of accuracy in space, on a staggered grid [9]. Here we consider flows with incompressibility and solid constraints for an horizontal fluid flow [3]. Results of this study are presented for the Navier-Stokes equations in order to show the efficiency of the method for complex fluid flows.
