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…
Data-driven framework for input/output lookup tables reduction: Application to hypersonic flows in chemical non-equilibrium
Clément Scherding, Georgios Rigas, Denis Sipp +2
In this paper, we present a novel model-agnostic machine learning technique to extract a reduced thermochemical model for reacting hypersonic flows simulation. A first simulation g…
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…
