Linear and Nonlinear Latent-Space Reduced-Order Models for the Rayleigh--Taylor Instability
Téo Granger, Balu Nadiga, Benoît-Joseph Gréa +2
We use a large database of direct numerical simulations to investigate the transition of the Rayleigh--Taylor instability to turbulence and its evolution toward a late-time self-si…

Learning Turbulence Closures with Physics-Informed Neural Networks for the Rayleigh-Taylor Transition to Turbulence
Paul Creusy, Benoît-Joseph Gréa, Antoine Briard +1
Reynolds-averaged Navier-Stokes (RANS) turbulence models are known to perform poorly in predicting the dynamics of Rayleigh-Taylor mixing when turbulence is not fully developed, pa…

Static and dynamic properties of multi-ionic plasma mixtures
Jean Clerouin, Philippe Arnault, Benoit-Joseph Grea +6
Complex plasma mixtures with three or more components are often encountered in astrophysics or in inertial confinement fusion (ICF) experiments. For mixtures containing species wit…
