Submesoscale and boundary layer turbulence under mesoscale forcing in the upper ocean
S. Peng, S. Silvestri, A. Bodner
The interaction among quasi-geostrophic mesoscale eddies, submesoscale fronts, and boundary layer turbulence (BLT) is a central problem in upper ocean dynamics. We investigate thes…
Physics-Constrained Neural Closure for Lattice Boltzmann Large-Eddy Simulation
Muhammad Idrees Khan, Sauro Succi, Hua-Dong Yao +1
We present a physics-constrained, data-driven subgrid-scale (SGS) stress closure for large-eddy simulation (LES) in the lattice Boltzmann method (LBM). Trained on filtered-downsamp…
A theoretical model for oceanic submesoscales under next-order effects of strain and turbulence
Shirui Peng, Abigail Bodner
Submesoscale currents in the oceanic mixed layer, comprising fronts, eddies, and filaments, are characterized by Rossby numbers (Ro). These features, which constant…
Validating the Boltzmann approach to the Large-Eddy simulations of forced homogeneous incompressible turbulence
Muhammad Idrees Khan, Sauro Succi, Giacomo Falcucci
The simulation of turbulent flows remains a central challenge, as even our most powerful computers cannot resolve the finest scales of motion in many flows of practical interest. A…
