is there any documentation specifying the valid range of y+ value for each turbulence model and each wall treatment method?

in specific I am looking for the valid rang for RSM for standard wall function and enhance wall treatment.

Both standard and enhanced wall treatment works for all y+.


The low y+ only and high y+ only models are hidden behind expert options.

You cant find for each model because y+,u+ relation is based on turbulence physics and not based on model equations. But you will find the valid region of different wall functions and wall integration. Low Reynolds number turbulence models can integrate up to viscous sub layer, RSM should belong to that. But it doesn't mean for high y+ it will not apply wall function. Most of the latest software adapts to the mesh y+ to give best solution.
