Abstract: Summary The work deals with numerical testing of two different numerical methods based on finite volumes (FV) and finite elements (FE) for different Reynolds numbers. The finite volume method is based on upwind scheme (third order) for convective terms and central second order for dissipative terms. Finite element method consists of stabilization of weak formulation for higher Reynolds numbers with the help of streamline-upwind (Petrov-Galerkin) modification. Authors compare both numerical results with experiment for laminar Re ∈ (100, 700), where steady solution exists, using the length of separation domain on lower wall as well as on upper wall for Re ≥ 400.
