Sub-Grid Scale Models -- CFD Online Discussion Forums

H Guest Posts: n/a	Hi! I understand 3 subgrid models are available in Fluent for LES, here are my questions: 1) Smagorinsky-Lilly --> what does the coefficient Cs represent? 2) Wall adapting local eddy viscosity --? what does the coefficient Cw represent? 3) What is the effect of adjusting these coeffs & which coeffs to use for modelling an impining jet? 3) What are the benefits/disadvantages of each for modeling an impinging jet? Thanks! H
