If I understood SST, it works quite fine at all y+ conditions (this is the reason why using SST instead of k-Omega). If you have y+ < 1, then k -> fixedValue, very small (1e-9) Omega ->...

We use to compare some flow data (wall cp, boundary layer profiles, wake profiles) against some experimental data that we have. We have also comparison with other codes on the same problems. My y+ is...

I've implemented the Menter's omega wall b.c. (Menter, AIAA Journal Vol 32 No 8, 1994), and I used it with kWall = 0 and nutWall =...
