Maybe I have not well understood your question, but for what I see the term b) is in divergence form, thus I don't see particular problems to insert it in a finite volume constest... is the additional flux ... |

The procedure to calculate the flux requires first the calculation of (which involves also an interpolation from points at the cell center to point at boarder-cell surface centers) and then a second interpolation to the surface centers. When I look at the TKE for RANS, this term is never present, so I was wondering if it is usually neglected for some reason or incorporated in some other term in some way. Of course, if not, the solution will be to compute the flux! =) |

I never worked personally on LES modelling supplied by the kinetic energy equation, I suggest to have a look at the book of Sagaut, you can find the TKE equation and have an idea of the modelling approximations |
