Numerical investigation of bleed on three-dimensional turbulent interactions due to sharp fins

Abstract. A combined theoretical and experimental study is presented for the in~teraction between crossing shock waves generated by (10% 10 ~ sharp fins and a flat plate turbulent boundary layer at Mach 8.3. The theoretical model is the full 3-D mean compressible Reynolds-averaged NavierStokes (RANS) eqtuations incorporating the algebraic turbulent eddy viscosity model of Baldwin and Lomax. A grid refinement study indicated that adequate resolution of the flowfield has been achieved. Computed results agree well with experiment for surface pressure and surface flow patterns and for pitot pressure and yaw angle profiles in the flowfield. The computations, however, significantly overpredic, surface heat transfer. Analysis of the computed flowfield results indicates the formation of complex streamline and wave structures within the interaction region.
