Numerical solution of the compressible turbulent flow through the gap caused by the incorrect contact of screw surfaces
Vimmr J., Švígler J.
pages 339 - +9p., full text

The paper deals with the numerical simulation of a turbulent compressible fluid flow through the two-dimensional model of a gap caused by the incorrect contact of screw surfaces. The incorrect contact of screw surfaces considered in this paper is caused by a large parallel displacement of the axis of one of the surfaces. Numerical solution of the nonlinear conservative system of the Favre-averaged Navier-Stokes equations is obtained by means of the cell-centred finite volume formulation of the explicit two-step TVD MacCormack scheme proposed by Causon on a structured quadrilateral grid. To simulate the turbulence effects the algebraic Baldwin-Lomax turbulence model is implemented into the own developed numerical code.
