y plus range

keeper · February 10, 2011, 10:01

Hello everyone.

I was searching ranges of y+ for each turbulence ,odel but I could not find it.

Can someone give me an advice where could I find it please??

Thanks for any suggestions.

y+ applies to wall boundary modelling, so is of more relevance to the wall function approach than the turbulence model. Simply put, y+<1 means you are integrating to the wall and y+ means you are using wall functions.
