Real Gas Effects on Receptivity to Roughness in Hypersonic Swept Blunt Flat-Plate Boundary Layers

Aerospace
Temperatures within the boundary layers of high-enthalpy hypersonic flows can soar to thousands or even tens of thousands of degrees, leading to significant real gas phenomena.

A numerical scheme for hypersonic turbulent flow : AIAA 2015-3341

, 2015
When it comes to simulate hypersonic flows, gas-kinetic schemes provide one distinct advantage over conventional Navier-Stokes schemes: they are able to handle rarefaction in a “natural” way; they can for instance provide a natural slip wall boundary ...

Investigation of computational techniques for the prediction of supersonic dynamic flows [PDF]

, 1999
A computational investigation was undertaken to examine techniques for predicting supersonic dynamic flows, involving unsteadiness over fixed and moving surfaces. The fixed geometries examined were cylinder-flares and compression ramps, and the moving
