Hi everyone,

I had a conceptual question on how to implement wall model to LES code.
I need to add wall model (wall stress model not RANS) to my LES code.

My conceptual question is: We know a Wall model calculates shear stress. How? (possibly explicitly from eddy viscosity from LES or etc.?)

Then we need to use that as B.C. to LES? How?

Thank you in advance for your useful comments.

Hi, have you already seen the book of Sagaut?

No, I have not.

I am just about to start studying wall modelling and then I should embed the model to my code.

Do you mean LES for incomp. flows of Sagaut?
