Receptivity of swept-aerofoil flows to small amplitude wall roughness using resolvent analysis based on wall displacement
Euryale Kitzinger, Denis Sipp, Olivier Marquet +1
The receptivity of a laminar boundary layer flow to small amplitude wall roughness is investigated on an ONERA-D swept aerofoil by introducing a dedicated resolvent operator based…
RONAALP: Reduced-Order Nonlinear Approximation with Active Learning Procedure
Clément Scherding, Georgios Rigas, Denis Sipp +2
Many engineering applications rely on the evaluation of expensive, non-linear high-dimensional functions. In this paper, we propose the RONAALP algorithm (Reduced Order Nonlinear A…
Mori-Zwanzig latent space Koopman closure for nonlinear autoencoder
Priyam Gupta, Peter J. Schmid, Denis Sipp +2
The Koopman operator presents an attractive approach to achieve global linearization of nonlinear systems, making it a valuable method for simplifying the understanding of complex…
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…
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…
