Mean resolvent operator of statistically steady flows
Colin Leclercq, Denis Sipp
This paper introduces a new operator relevant to input-output analysis of flows in a statistically steady regime far from the steady base flow: the mean resolvent . I…
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…
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…
Nonlinear waves in stratified Taylor--Couette flow. Part 2. Buoyancy flux
Colin Leclercq, Jamie L. Partridge, Colm-Cille P. Caulfield +2
This paper is the second part of a two-fold study of mixing, i.e. the formation of layers and upwelling of buoyancy, in axially stratified Taylor--Couette flow, with fixed outer cy…
Nonlinear waves in stratified Taylor--Couette flow. Part 1. Layer formation
Colin Leclercq, Jamie L. Partridge, Pierre Augier +3
This paper is the first part of a two-fold study of mixing, i.e. the formation of layers and upwelling of buoyancy, in axially stratified Taylor--Couette flow, with fixed outer cyl…
Connections between centrifugal, stratorotational and radiative instabilities in viscous Taylor-Couette flow
Colin Leclercq, Florian Nguyen, Rich R. Kerswell
The `Rayleigh line' , where and are respectively the rotation and radius ratios between inner (subscript `i') and outer (subscript `o') cylinders, is…
