Just curious, when specifying constant heat flux bc for the wall, does the wall temperature vary with Y+ values.
I ran test cases of flow insided heated tube and noticed that for LowRe settings, I had to use a Y+<<1 eg., Y+=0.02 to get mesh converged wall temperature results. For regular wall function approach, Y+>30, the wall temperatures always varied with Y+ values. For alpha wall function, I used the alphajayatilleke. Any insight is much appreciated. Cheers, arvind |
