This contribution is devoted to a turbulent compressible fluid flow computation through a 2‐D model of the male rotor‐housing gap in screw compressors. For the numerical solution of the nonlinear conservative system of the Favre‐averaged Navier‐Stokes equations the cell‐centred finite volume formulation of the explicit two‐step TVD MacCormack scheme proposed by Causon on a structured quadrilateral grid is used. The turbulent viscosity is calculated by using the algebraic Baldwin‐Lomax turbulence model which is implemented into the own developed numerical code. (© 2005 WILEY‐VCH Verlag GmbH & Co.
