Reynolds effects on transition to turbulence for hypersonic expansion and compression corner flows
Clément Caillaud, Mathieu Lugrin, Nicolas Severac +1
This experimental and numerical study examines transition to turbulence for a Cone-Cylinder-Flare geometry at Mach 7 and across a broad Reynolds number range. The focus is set on b…

A Review of the Design of Cone-Cylinder-Flare Geometries for Stability Analyses and Conventional/Quiet Wind Tunnel Tests
Sebastien Esquieu, Steven P. Schneider, Elizabeth K. Benitez +1
In order to study the effects of pressure gradients, flow expansion, and recompression on the stability of hypersonic boundary-layers, axisymmetric cone-cylinder-flare configuratio…

Transition mechanisms in hypersonic wind-tunnel nozzles: a methodological approach using global linear stability analysis
Hugo Lemarquand, Mathieu Lugrin, Cédric Content +3
Base-flow computations and stability analyses are performed for a hypersonic wind tunnel nozzle at a Mach number of 6. Isothermal and adiabatic wall boundary conditions are investi…
