Effect of Reynolds number on a normal shock wave-transitional boundary-layer interaction over a curved surface

Shock Wave / Boundary Layer Interaction Experiment on Control Surface

The shock wave / boundary layer interaction (SWBLI) experiment is part of the EXPERT mission. SWBLI is studied on two identical fixed compression ramps made of C/SiC, which are models for control surfaces. The flow separates on the flat surfaces upstream of the compression ramps and reattaches on the ramp surfaces. A reattachment shock results, which interacts with the boundary layer. One ramp ...

Evaluation of Local Effects of Transitional Knudsen Number on Shock Wave Boundary Layer Interactions

Effect of Rotation and Stiffness on Surface Wave Propagation in a Elastic Layer Lying Over a Generalized Thermodiffusive Elastic Half-Space with Imperfect Boundary

The present investigation is to study the surface waves propagation with imperfect boundary between an isotropic elastic layer of finite thickness and a homogenous isotropic thermodiffusive elastic half- space with rotation in the context of Green-Lindsay (G-L model) theory. The secular equation for surface waves in compact form is derived after developing the mathematical model. The phase velo...

Numerical Simulation of Shock-Wave/Boundary/Layer Interactions in a Hypersonic Compression Corner Flow

Numerical results are presented for the shock-boundary layer interactions in a hypersonic flow over a sharp leading edge compression corner. In this study, a second- order Godunov type scheme based on solving a Generalized Riemann Problem (GRP) at each cell interface is used to solve thin shear layer approximation of laminar Navier-Stokes (N-S) equations. The calculated flow-field shows general...

The Interaction between a Weak Normal Shock Wave and a Turbulent Boundary Layer

SUMMARY A theory is presented for the interaction between a weak normal shock in an initially uniform mainstream, and an idealised boundary layer, with frictionless, one-dimensional, subsonic flow, on a flat wall. Reasons are given for believing that, despite the drastic simplifications of the model, it is not altogether unreal. Hence it is hoped that the results will prove helpful in interpret...
