Insights Into the Unsteady Shock Boundary Layer Interaction
Volume 10A: Turbomachinery — Axial Flow Fan and Compressor Aerodynamics, 2022Abstract The flow through a transonic compressor cascade is characterized by high unsteadiness due to the shock boundary layer interaction. Investigations in recent years have shown that a detailed understanding of the causes of unsteady shock oscillation is necessary to develop successful approaches to influence it.

Aeroacoustics of transonic shock-boundary layer interactions
13th AIAA/CEAS Aeroacoustics Conference (28th AIAA Aeroacoustics Conference), 2007The interaction of a spatially developing supersonic turbulent boundary layer with a normal shock wave is analyzed by means of direct numerical simulation of the compressible Navier-Stokes equations. At the selected flow conditions, corresponding to a mild shock, no mean flow separation is observed.

Manipulation of Shock/Boundary-Layer Interactions in Hypersonic Inlets
Journal of Propulsion and Power, 2001Possibilities to manipulate shock/boundary layer interactions are demonstrated with regard to an application for hypersonic inlets. Experiments on generic models have been carried out in the hypersonic wind tunnel H2K of DLR at Mach number 6 and laminar flow conditions. Experimental results were validated by numerical flow simulations using a 2D finite

Initial conditions for the hypersonic-shock/boundary-layer interaction problem.
AIAA Journal, 1973Boundary layers interacting with a hypersonic mainstream over hot and cold flat plates are solved numerically using an implicit finite-difference scheme. Attention is given to the details of the initialization procedure needed to allow subcritical boundary-layer development.

Control plate for shock-boundary layer interaction
Shear Flow Control Conference, 1985Paper describes tests and computations for a relatively unique technique to greatly reduce/eliminate the separation region for shock-boundary layer interactions. A number of studies have shown that the usual effects of such interactions include increased local heating and wall pressures, thickening of the boundary layer and a decrease in the momentum ...

Simulations of Incident Shock Boundary Layer Interactions
54th AIAA Aerospace Sciences Meeting, 2016© 2016, American Institute of Aeronautics and Astronautics Inc, AIAA. All Rights Reserved. We examine the effects of varying the tunnel width to height ratio, the boundary layer thickness, and the incident shock angle on the shock boundary layer interaction of an incident oblique shock with a turbulent boundary layer.

Hypersonic shock/boundary-layer interaction database
22nd Fluid Dynamics, Plasma Dynamics and Lasers Conference, 1991Turbulence modeling is generally recognized as the major problem obstructing further advances in computational fluid dynamics (CFD). A closed solution of the governing Navier-Stokes equations for turbulent flows of practical consequence is still far beyond grasp. At the same time, the simplified models of turbulence which are used to achieve closure of

Wavelet analysis of supersonic shock-boundary-layer interaction
Physics of Fluids, 2023We present a wavelet analysis of supersonic shock-boundary-layer interaction. We have used direct numerical simulation data for supersonic flow over a compression ramp and performed orthogonal anisotropic wavelets. The wavelet-based method of extracting coherent structures is applied to the flow vorticity field, decomposed into coherent and incoherent ...
