SA Turbulence model implementation
I am presently working on implementing Spallart-Allmaras model in my compressible solver. I have the following queries
1. Which is a better option: Coupled or Decoupled ? 2. Are there any fixes/limiters needed, such as production limited as 20 times destruction and so on ? 3. Is viscous flux linearisation really essential ? Does it affect convergence on very fine grids ?
Any suggestions/comments are most appreciated.
Reagdrs and Thanks in advance,
