Temperature boundary layer

Hello CFD lovers
I am working with a flow case involving convective heat transfer. I the use k-epsilon model and standard wall functions. My wall y+ values are within the region 100-150. This is ok for the velocity boundary layer when using standard wall functions but I am not sure if it is okay for the temperature boundary layer. I think I have read somewhere that y+ should not exceed 100 for the temperature law-of-the-wall. Can anyone with experience in this field give me some advice or give me a hint where I can find more info about this? Thanks in advance Conny L |

Actually, y+ should be between 30 and 60 for both velocity and temperature boundary layer. And it's better to keep y+ close to 30 (see FLUENT manual).
You should find more info in this book: Turbulence Modelling for CFD D.C. Wilcox 1993 ISBN 0-9636051-0-0 For a list of books about CFD visit for example this site: http://icemcfd.com/cfd/CFD_books.html Hi ap |
