I want to make a mesh which heve near the wall (y+>30) for apply k-e model. How can i compute the Y length (length from wall to first node) for i make in Gambit (with the first length mesh) the mesh of geometry?

http://geolab.larc.nasa.gov/APPS/YPlus/ you can use this page to calculate the first mesh height y!

it depends on your issue. you may reference other books about viscous fluid dynamics. I have not simulate that problem, so I can't tell you the non dimentional length.
Good luck, xinboy, |
