| Résumé : | The implicit approximate factorization scheme of Beam-Warming has been coded to solve the compressible Navier-Stokes equations for the three dimensional interaction caused by a swept oblique shock wave normal to a laminar boundary layer. The shock generator compression angle was 6 degree and the Mach and Reynolds numbers were 2. 25 and 108,000 respectively. Two meshes were used successively to study the influence of the mesh spacing. The numerical results reproduce the essential features of the flow field, namely the extended separation of the boundary layer and the conical nature of the interaction footprint. In addition, they clearly indicate the presence of an elongated vortical structure beneath the outer shock wave. (Author abstract. ) |
