| Abstract: | A numerical solution of two dimensional channel flow with a sudden expansion is obtained by solving the Navier Stokes equations according to the finite analytic method.The flow patterns predicted for the free flow with the Reynolds numbers, Re ,of 25,50,100,150 and 200.Satisfactory results are obtained as well for the recirculation zone and the re attachment length. |
