The Interaction Between -Shock Waves and Boundary Layers

The interaction betWeen shock v,aves and boundary layers has important effects in msny problems of high-speed flcv?. This paper has been Written as a guide to the litcraturc On the subject, and as a critical review of the present state of lmc~llcdgo concerning both the underlying physical processes and the practical applications. It rvill be clear to the reader that, although substantisl prcgrc...

Incipient Separation in Shock Wave / Boundary Layer Interactions as Induced by Sharp Fin

The incipient separation induced by the shock wave/ turbulent boundary layer interaction at the sharp fin is the subject of present study. Existing theories for the prediction of incipient separation, such as those put forward by McCabe (1966) and Dou and Deng (1992), can have thus far only predicting the direction of surface streamline and tend to over-predict the incipient separation conditio...

DNS of unsteady shock boundary layer interaction

A novel numerical scheme has been developed to simulate high speed viscous flows in complex geometries using unstructured grids. A characteristic–filter based shock capturing scheme is applied as a corrector step to a non–dissipative predictor scheme. This algorithm is being used to study shock turbulent boundary layer interactions and this paper presents the results of a turbulent flow at Mach...

Shock-boundary Layer Interaction (sbli) Cfd Research and Applications

Preamble Interaction of shock waves with turbulent boundary layers is important in many aerospace applications. Examples in external aerodynamics include control surfaces, wing body junctions, and multi-body aerodynamics. In high-speed propulsion systems, shock-boundary layer interaction (SBLI) can occur in intakes, supersonic combustion chambers and nozzles. Computational fluid dynamics (CFD) ...
