An introduction to the (original) 1963 Smagorinsky model for Large Eddy Simulation (LES). The talk is broken down into the following sections:
1) 07:22 How is the sub-grid kinematic viscosity (nu_sgs) calculated?
2) 09:47 What is the sub-grid velocity scale (U0) and how is it calculated?
3) 21:38 What is the sub-grid length scale (l0) and how is it calculated?
4) 28:09 What is the Smagorinsky Coefficient (Cs) and how is it calculated?
5) 35:52 What are some of the problems with the (original) 1963 Smagorinsky Model?
