Development of a large-eddy simulation subgrid model based on artificial neural networks: a case study of turbulent channel flow [PDF]
Geoscientific Model Development, 2021 Atmospheric boundary layers and other wall-bounded flows are often simulated with the large-eddy simulation (LES) technique, which relies on subgrid-scale (SGS) models to parameterize the smallest scales.
