is there a yStarRAS tool?
Hi
is there a tool for y* like y+? |
Hi Ehsan,
AFAIK, there isn't one. Uhm... didn't you make this bug report: http://www.openfoam.org/mantisbt/view.php?id=835 Here's a very old bug report also on this topic: http://www.cfd-online.com/Forums/ope...-vs-ystar.html - but the answers you got on your bug report was better. In the mean time, I also found this: http://www.cfd-online.com/Forums/ope...tml#post424723 - post #4 - which was in response to a similar question of yours from a month ago. So the very big question is: which "yStar" are you looking for? The only references I found in OpenFOAM's own source code was in these files: Code:
src/turbulenceModels/incompressible/RAS/LienLeschzinerLowRe/LienLeschzinerLowRe.C Code:
yStar_ = sqrt(k_)*y_/nu() + SMALL Bruno |
thanks.I wanted to be confident about this subject.
----------------------------------- (For Summary): ------------------------ well then yPlusRAS acts as a y* function that is suitable in high-Re turbulent simulation(when the first cell center is in logarithmic region of turbulent boundary layer) but yPlus tool that is created by cfd-online users is used when we have low-Re meshes(when first cell center is in laminar-sub layer region of turbulent boundary layer) :) |
Looking to calculate yStarRAS too
