A one-step difference scheme for solving the Navier-Stokes equations is discussed. Three hnprovements on this scheme are given: scheme with control factor, seheme with upwind computation and implicit factored scheme. Numerical experiments for the nonlinear Burgers equation are made and the results are compared with the solutions of explicit and implicit MacCormack scheme. The implicit factored scheme is shown to be most effective.
