Turbulent frequency equation for compressible kOmegaSST turbulence model (F1)
 
Hi,

According to the kOmegaSST.C file (line 470), turbulent frequency equation term is:

fvm::SuSp
(
rho_*(F1 - scalar(1))*CDkOmega/omega_,
omega_
)

but in the following source papers as described in kOmegaSST.H file:

1. Menter, F., Esch, T.
"Elements of Industrial Heat Transfer Prediction"
16th Brazilian Congress of Mechanical Engineering (COBEM),
Nov. 2001

and

2. Hellsten, A.
"Some Improvements in Menterís k-omega-SST turbulence model"
29th AIAA Fluid Dynamics Conference,
AIAA-98-2554,
June 1998.

there is a member (scalar(1) - F1) which doesn't look like in the kOmegaSST.C file.


Does it have to be treated like bug, or something else...?

Regards!

Minus sign in kOmegaSST
 
Sorry people, I haven't seen that there is an "minus" sign in "omega" equation, so F1 and scalar(1) change their places. :)
