High speed flow with Launder-Sharma-k-epsilon-Model

I need to run a compressible high speed nozzle flow in OF on a low-Re mesh (y+<1).
So far I did my calculations with the kOmegaSST turbulence model and it worked quite nice.
Now I have to use the k-Epsilon turbulence model on the same mesh.
The only low-Re k-epsilon turbulence for a compressible case available in OF is the one by Launder and Sharma.
I compared the code of the LaunderSharmaKE with the standard kEpsilon model and found some differences as additional source-terms as well as some turbulent Reynolds-number functions.
So I have some questions, hoping anybody can answer these:
Thanks in advance!
