Default Sub-Grid Scale Models

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
