Interaction of a moving shock wave with a turbulent boundary layer

چکیده

In the present study, influence of a uniformly moving impinging shock on resulting wave–turbulent boundary layer interaction is numerically investigated. The relative Mach number front travelling above flat-plate model varied between 0 and 2.3, while quasi-steady inflow conditions remained constant with 3. To quantitatively evaluate effect speed, well-known scaling method for length in flows was applied as reference after significant improvements modelling effects Reynolds wall temperature using new existing data. Moreover, previously obtained experimental results limited range speeds were employed to validate numerical results. Three ranges distinctly different properties extracted described developed correlation-based approach built extended quasi-stationary law. first range, scaled reaches its maximum given strength can be directly by law interactions. second travelling-speed dependence explicitly influenced movement. With increasing here decreases significantly faster than case. end this speed reached when absolute has caught up sound zone, thus fallen zero. This limit signifies transition third where upstream no longer possible.

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...

Wall modeled large-eddy simulation of shock wave/turbulent boundary layer interaction with separation

The objective of this work is to assess the ability of large-eddy simulations employing an equilibrium wall model to reproduce the flow features present in strong interactions between an oblique shock wave and the turbulent boundary layers of an internal (duct) flow leading to mean flow separation. Such interactions (denoted STBLI) are pertinent, among other applications, to supersonic flight p...

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...
