qutadah.r is on a distinguished road
I have a question to the theory of wall functions and how the plot should look like, I found some various plots where they differ in how the log-law extension intersects the u+ axis, and various log-law slope variations. Now I know it differs depending on various factors (density, skin friction, wall shear stress, etc.) But I would like to know if there is a "wrong" plot or if there is some criteria I should look for to make sure qualitatively my plot is correct.

Thanks!
