Adjoint-based linear sensitivity of a hypersonic boundary layer to steady wall blowing-suction/heating-cooling
Arthur Poulain, Cédric Content, Georgios Rigas +2
For a Mach 4.5 flat-plate adiabatic boundary layer, we study the sensitivity of the first, second Mack modes and streaks to steady wall-normal blowing/suction and wall heat flux. T…
Reactive control of 2 nd Mack mode in a supersonic boundary layer with freestream velocity/density variations
Pierre Nibourel, Colin Leclercq, Fabrice Demourant +2
We consider closed-loop control of a two-dimensional supersonic boundary layer at M = 4.5 that aims at reducing the linear growth of second Mack mode instabilities. These instabili…
BROADCAST: A high-order compressible CFD toolbox for stability and sensitivity using Algorithmic Differentiation
Arthur Poulain, Cedric Content, Denis Sipp +2
The evolution of any complex dynamical system is described by its state derivative operators. However, the extraction of the exact N-order state derivative operators is often inacc…
Transition scenario in hypersonic axisymmetrical compression ramp flow
Mathieu Lugrin, Samir Beneddine, Colin Leclercq +2
A high-fidelity simulation of the shock/transitional boundary layer interaction caused by a 15-degrees axisymmetrical compression ramp is performed at a freestream Mach number of 5…
