AbstractA Preconditioning method is introduced to the NS solver based on the dual-time iteration for unsteady compressible flows. This method balances the eigenvalues of NS equations, reduces the stiffness of compressible NS solver for low-speed flow, and increases the capabilities of the solver for low speed flow. By comparing the numerical results for the flow around cylinder at 5m/s with the experiment data, a good agreement was obtained with a discrepancy of about 5%.
