How to solve this formula?
I am a newbie on this model. I need you help on this. This is a model called gao-yong turbulence model.
"Partial-average-based equations of in-compressible turbulent flow"
Ge Gao. Yan Yong.
In this model, we have a equation like this:see the attached image.
We know u and p. tau can be expressed by vector l.
The right of this equation is a little different with the normal N-S equation. There is a vector l , and the whole right part, which is different with the N-S equation, is a inner product of two vectors. Im using FVM. So now I dont know how to discretize it. Any ideas will be appreciated. Thanks in advance.
Any ideas? Thanks.
A little progress:
In the equation I posted, I should solve the mag(l). But how? I dont know.
