Subgrid-scale Models for LES

This lecture covers subgrid-scale models for Large Eddy Simulation (LES), focusing on the Smagorinsky model developed in 1963 by Tobias Schneider. The instructor discusses the eddy viscosity concept and its application in turbulence modeling, emphasizing the analogy to mixing length theory. Various formulations of the Smagorinsky model are presented, highlighting the role of eddy viscosity in capturing turbulent flow phenomena. Additionally, the lecture touches on the Boussinesq hypothesis and its relevance to understanding turbulence. The content delves into the theoretical foundations of subgrid-scale modeling, providing insights into the complexities of turbulent flows and their numerical representation in LES simulations.
