Default enhanced once again
Posts: n/a
HI, experts.

1) As far as I've understood from Chen and Patel paper, the two-layer approach they offered with the use of info from Wolfstein is a closed form solution. Am I right? Is this approach actually used in Fluent together with k-e ans RSM?

2) Where the blending function of Kader are used? Are they restricted to k-w and LES in Fluent?

3) Is this right: using enhanced wall treatment with k-e requires y+~1 at all the walls.

4) Is the following correct: while using k-w one does not need to worry about y+ because there are blending function of Kader that bridge the wall to the main flow depending on the near-wall mesh resolution (adding be aware of not having the closest cell in the buffer).
