[CFD] The Smagorinsky Turbulence Model (Part 2)

Part 2 in the series on the Smagorinsky model for Large Eddy Simulation (LES). The talk is broken is down into the following sections: 1) 07:15 What happens close to the wall in the 1963 (Original) Smagorinsky model? 2) 14:25 How can the 1963 (Original) Smagorinsky model be modified to improve the near wall behaviour? 3) 19:17 How does the eddy size reduce in the logarithmic region? 3) 31:50 What is the Van Driest damping function and how does it reduce the eddy size in the viscous sub-layer and buffer regions? #smagorinsky #vandriest #fluidmechanics101 ============================================ Some useful references: 1) S.
