LES models and relative coefficients

ArathoN · February 6, 2014, 15:30

Hi foamers,

I decided to look on how to use the LES models but I'm stuck with how i can determine all the LES coefficient (and for some i don't even know what they are for), i tried to search in this forum and also in some report/publications (where i found the meaning of some of the coefficients live the Driest one).

Do any of you have any useful link or anything related like reports and suck. It's always appreciated if you could explain it to me.

No one has any useful imformation?

I understood almost everything but these two variable :

Code:

 deltaCoeff      1;

Code:

Cdelta          0.158;

What does they mean? and what do they influence?

no one has an idea about these coefficients?
