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…
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…
Effect of streaks on hypersonic boundary layer instability
Clément Caillaud, Guillaume Lehnasch, Eduardo Martini +1
Hypersonic boundary layers exhibit diverse transition pathways, influenced by various flow conditions and environments. Non-modal mechanisms, such as the lift-up effect, are recogn…
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…
