Code production of k ?

The production of kinetic energy near wall cell is referred by which paper?
G0[celli] += w *(nutw[facei] + nuw[facei]) *magGradUw[facei] *Cmu25*sqrt(k[celli]) /(kappa_*y[facei]);
I found Spalding's formula is not the same as above (Pk =Cmu^0.25Utau^2U/y). Anybody knows this issue?


@东岳 Many thanks. In fact, I understood this procedure. One confusion is that the formula implemented in openfoam is not consistent with that mentioned in the Spalding' paper.

Nobody is interested in this issue?
