Difference kmutWallFunction - mutUSpaldingWallFunction

CellZone · October 21, 2016, 08:58

Hi,

i really hope for some answers on this topic:

I am using k-w-SST in my simulation. Now I can choose between

a) compressible::kmutWallFunction

b) mutUSpaldingWallFunction

1. What is the difference between those wall functions?

2. Does this difference have some influence on using it with k-w-SST?

Since OpenFOAM automatically switches between solving the near wall region and using a wall function there should be no big difference?

Thank you for your help!!

Very Much!

Moritz
