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…

Perturbation amplification near the stagnation point of blunt bodies
Eduardo Martini, Clement Caillaud, Guillaume Lehnasch +2
Different transition to turbulence routes for the flow around blunt bodies are possible. Non-modal amplification of perturbations via the lift-up effect has recently been explored…

Global stability analysis of a hypersonic cone-cylinder-flare geometry
Clément Caillaud, Mathieu Lugrin, Sébastien Esquieu +1
Characterizing the boundary layer transition to turbulence around realistic hypersonic vehicles is a challenging task due to the numerous parameters that affect the process. To add…
