| Abstract: | The preconditioning methods are used for solving two-dimensional compressible Navier-Stokes equations and an all-speed flow field numerical simulation method which can be used for both low-speed flows and compressible flows is developed.Ausm family schemes and multi-step Runge-Kutta time marching method are utilized to discretize Navier-Stokes equations.Numerical simulation results of flow field of a Bump,RAE2822 airfoil and multi-element high lift airfoil at different speeds are presented and are compared ... |
