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…
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,…
