Nonequilibrium Real-gas Effects on Disturbance/bow Shock Interaction in Hypersonic Flow past a Cylinder

The interaction of free-stream disturbances and the bow shock wave in hypersonic ow past a blunt leading edge is an important part of hypersonic boundary layer receptivity to free-stream disturbances. It has been shown that, for a perfect gas, the back and forth interaction and reeection of acoustic waves behind the shock greatly amplify the magnitudes of the disturbance waves. The interaction ...

Highly rarefied two-dimensional jet impingement on a flat plate

In this paper, we investigate highly rarefied jet gas flows out of a two-dimensional slit that impinges on a flat plate which is set vertically to the plume flow direction. The plate is assumed to be completely diffusive and the gaseous plume flow out of the slit is modeled with a Maxwellian distribution function which is characterized with known number density, nonzero exit velocity, and tempe...

Transition of hypersonic flow past flat plate with roughness elements

Roughness elements in high speed flows can cause laminar-turbulent transition leading to higher heating rates and drag. Transition of flow past a hemispherical bump placed on a flat plate is explored in this paper for three Mach numbers [3.37, 5.26, 8.23] using direct numerical simulation on unstructured grids. The simulation parameters are chosen to match the experiments carried out by Danehy ...

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...
