Data-driven modeling of hypersonic flows in chemical non-equilibrium with catalytic surfaces
Konstantinos Sarras, Louis Walpot, Thierry Magin +2
Hypersonic flows involve extreme thermochemical non-equilibrium, where strong energy dissipation leads to tightly coupled chemical reactions, radiation, and energy exchange. In thi…
Linear stability of Poiseuille flow over a steady spanwise Stokes layer
Daniele Massaro, Fulvio Martinelli, Peter J. Schmid +1
The temporal linear stability of plane Poiseuille flow modified by spanwise forcing applied at the walls is considered. The forcing consists of a stationary streamwise distribution…
Reduced Markovian Models of Dynamical Systems
Ludovico Theo Giorgini, Andre N. Souza, Peter J. Schmid
Leveraging recent work on data-driven methods for constructing a finite state space Markov process from dynamical systems, we address two problems for obtaining further reduced sta…
Development of a high-fidelity computational tool for chemically reacting hypersonic flow simulations
Athanasios T. Margaritis, Clément Scherding, Olaf Marxen +2
In this paper, we present a methodology to achieve high-fidelity simulations of chemically reacting hypersonic flows and demonstrate our numerical solver's capabilities on a select…
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…
A Comprehensive Study of Adjoint-Based Optimization of Non-Linear Systems with Application to Burgers' Equation
Alexandru Fikl, Vincent Le Chenadec, Taraneh Sayadi +1
In the context of adjoint-based optimization, nonlinear conservation laws pose significant problems regarding the existence and uniqueness of both direct and adjoint solutions, as…
