1/ PHOENICS has quite a few turb models, but not all are valid if using parsol as they were written before and haven't yet been redeveloped.

2/ What have other people used in the literature?

3/ Do what they have. I think that if you use KE models then the YPLS value should be > 11.63 so that the near wall cell is in a turbulent region, otherwise the cell will be in the laminar sublayer and the log-law wall function will not be valid.

Sorry this isn't much!

Perhaps there is a relevant paper in the PHOENICS journal, I don't know how to find out though.

Google can often be of help... http://in3.dem.ist.utl.pt/downloads/lxlaser2000/
