| Abstract: | Based on the compressible Navier Stokes equation, subsonic and supersonic turbulent backward facing step flows are computed by using Beam Warming vector splitting form and van Leer flux vector splitting method through Baldwin Lomax algebraic turbulence model and Johnson King non equilibrium algebraic turbulence model. Good agreement with experimental results is achieved. |

| Keywords: | backward facing step flow turbulence model vector splitting form |
