Numerical simulation of oblique shock-wave/vortex interaction
High Reynolds number supersonic flowfields were generated numerically by integration of the time-dependent three-dimensional compressible Euler and mass-averaged Navier-Stokes equations in order to simulate the interaction of a streamwise vortex with an oblique shock wave. The vortex develops at the tip of a vortex-generating fin which is suspended from the ceiling of a wind tunnel. Downstream, an oblique shock wave is produced by a wing surface which spans the width of the wind tunnel and has a two-dimensional sharp leading-edge wedge as its airfoil section. Grid resolution studies are provided in order to assess accuracy of the solutions. Resultant features of the numerical flowfields are discussed ,and comparison is made with experimental data in terms of static pressure distributions on the wing surface.
