Résumé :

An investigation of an oblique shock wave/laminar boundary layer interaction is presented. The Mach number was 2. 15, the Reynolds number was 10**5 and the overall pressure ratio was 1. 55. The interation has been demonstrated to be laminar and nominally two-dimensional. Experimental results include pressure distributions on the plate and single component laser-Doppler velocimetry velocity measurements both in the attached and separated regions. The numerical results have been obtained by solving the full compressible Navier-Stokes equations with the implicit approximate factorization algorithm by Beam & Warming. Comparison with experimental data shows good agreement in terms of pressure distributions, positions of separation and reattachment and velocity profiles.
