A low diffusion E-CUSP (LDE) scheme for preconditioned Navier-Stokes equations is developed. With unfactored implicit Gauss-Seidel relaxation scheme for time integration, the LDE scheme with high-order WENO reconstruction is used to simulate several flows at various speed from low speed natural convection to supersonic flows. Numerical results are presented to show efficiency, accuracy and robustness of the new preconditioning scheme.
