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 equations1,3-5] and these results of the experiments6,7].The computations show that the numerical scheme in this paper is satisfactory. |
