Large eddy simulation

Large Eddy Simulation (LES) is a computational fluid dynamics technique used to simulate turbulent fluid flows. It is particularly effective for resolving the large-scale motions of turbulence while modeling the smaller-scale motions. ### Key Components of LES: 1. **Spatial Filtering**: In LES, the governing equations of fluid dynamics (like the Navier-Stokes equations) are filtered to separate the large eddies (large-scale turbulent structures) from the small eddies (small-scale turbulent structures).
