    Abstract

    Theory of non-oscillatory schemes lias been used in conjunction with a finite-volume cell-vertex Navier-Stokes solver in this paper, in order to compute compressible viscous flow Holds past airfoils which accurately capture shock without preshodc oscillutioris. The SLIP (symmetric limited positive) scheme with scalar splitting and with flux-difference splitting schemes proposed by Jaiueson(13; 1993) have been implemented here, These schemes have the LED (local extromum diminishing) property which is equivalent to that of TVD (total variation diminishing) in one-dimension. Typical transonic test cases have been studied. It is found that both the schemes provide very good shock resolution at high Mach numbers for steady solution of the viscous fluid How equations expressed13; by Reynolds averaged Navier-Stokes equations in conservation law form augmented with Baldwin-Lornax (1978) turbulence model.
