Simulation of three-dimensional shock/boundary-layer interaction in a single-fin configuration :

The three-dimensional single-fin configuration finds application in an intake geometry where the cowl-shock wave interacts with the side-wall boundary-layer. Reynolds-averaged Navier-Stokes computations using standard Spalart-Allmaras model is carried out for three-dimensional single-fin configuration with well documented experimental data. The flow-physics is studied in the complex region of swept-shock- wave turbulent boundary-layer interaction and is correlated to the wall pressure and skin-friction. Com- puted wall pressure and skin-friction is compared to the measurements. keywords : high speed flows; single-fin; shock wave; turbulent boundary-layer; separation bubble; turbulence modelling
