【Abstract】 In this paper, a mixed explicit-implicit scheme based on an antidiffusive method is used to solve the Navier-Stokes equations for the supersonic and hypersonic separated flows. The computations are performed for laminar and turbulent flows over the two- and three-dimensional compression corners. The obtained results are compared with the results of numerically computing NS equations[1,3-5land these results of the experiments[6’7]. The computations show that the numerical scheme in this paper is satisfactory.更多还原
