In this paper, an efficient and accurate method based on preconditioned AUSM scheme is studied. Turkel's preconditioning method in conjunction with secondorder finite-volume MUSCL-type AUSMDV and AUSM+-up scheme based on the primitive variables are used to solve Navier-Stokes equations. These two schemes used in CFD with or without preconditioning method are compared. The surface pressure distributions are compared with that calculated from central difference scheme. The preconditioning method used in this paper obtains an improved convergence, stability and the capability for the calculation of the low Mach number flows and transonic flows. The preconditioning high-resolution scheme strengthens the capability of identifying discontinuities and reducing the numerical dissipation. The present method that combines the multigrid algorithm accelerates further the convergence. Flow-independent convergence rates of the method are also observed from the numerical results for the low Mach number flows.
