Spalart-Allmaras for container ship optimization? Y/N?

mCiFlDk · March 13, 2021, 15:52

Hello Foamers,

The question I have is quite straight-forward:

Have you ever used the Spalart-Allmaras turbulence model for liquid-involved analyses? (i.e. ships, ducts, hydrofoils...) If so, does it behave correctly and is robust enough?

Thank you all for your time.

In my experience, it's not great for this kind of low Re flows if drag predictions are important for you.
