Large-eddy simulation and wall modelling of turbulent channel flow
D Chung, DI Pullin - Journal of fluid mechanics, 2009 - cambridge.org
We report large-eddy simulation (LES) of turbulent channel flow. This LES neither resolves
nor partially resolves the near-wall region. Instead, we develop a special near-wall subgrid …
