Receptivity and instability of the hypersonic flow over moderately blunt cones
N. d'Eprémesnil, C. Caillaud, G. Lehnasch +2
With a view to identifying and understanding the linear receptivity and amplification mechanisms that underpin laminar-to-turbulent transition over blunt bodies in hypersonic flow,…

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…

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…
