Summary0000085: kappatJayatillekeWallFunction: kappat calculation
DescriptionIn kappatJayatillekeWallFunction, when yPlus > yPlusTherm, the kappat is calculated from:

scalar kt = nu*(yPlus/(Prt_/kappa_*log(E_*yPlusTherm) + P) - 1/Pr)

I think the calculation should be:

scalar kt = nu*(yPlus/(Prt_*(log(E_*yPlus)/kappa_ + P)) - 1/Pr)

The modified calculation gives mesh independent results and matches results obtained with the formulation used in the alphaSgsJayatillekeWallFunction. Do you know a good reference for the formulations?
