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…
Mixing induced by Faraday surface waves
Andrés Castillo-Castellanos, Benoît-Joseph Gréa, Antoine Briard +1
We investigate how surface waves enhance mixing across the interface between two miscible fluids with a small density contrast. Imposing a vertical, time-periodic acceleration, we…
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…
Permanence of large eddies in variable-density homogeneous turbulence with small Mach numbers
Olivier Soulard, Jérôme Griffond, Benoît-Joseph Gréa +1
In this work, we study the large-scale structure of homogeneous flows displaying high density contrasts and small turbulent Mach numbers. Following Batchelor & Proudman (PTRSA 258,…
