      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.WeChat Screenshot_20200504110942.png

            Nobody is interested in this issue?
