Class
Foam::RASModels::kOmegaSSTSato
Group
grpRASTurbulence
Description
Implementation of the k-omega-SST turbulence model for dispersed bubbly
flows with Sato (1981) bubble induced turbulent viscosity model.
Bubble induced turbulent viscosity model described in:
\verbatim
Sato, Y., Sadatomi, M.
"Momentum and heat transfer in two-phase bubble flow - I, Theory"
International Journal of Multiphase FLow 7, pp. 167-177, 1981.
\endverbatim
Turbulence model described in:
\verbatim
Menter, F., Esch, T.
"Elements of Industrial Heat Transfer Prediction"
16th Brazilian Congress of Mechanical Engineering (COBEM),
Nov. 2001
\endverbatim
with the addition of the optional F3 term for rough walls from
\verbatim
Hellsten, A.
"Some Improvements in Menter’s k-omega-SST turbulence model"
29th AIAA Fluid Dynamics Conference,
AIAA-98-2554,
June 1998.
\endverbatim
Note that this implementation is written in terms of alpha diffusion
coefficients rather than the more traditional sigma (alpha = 1/sigma) so
that the blending can be applied to all coefficuients in a consistent
manner. The paper suggests that sigma is blended but this would not be
consistent with the blending of the k-epsilon and k-omega models.
Also note that the error in the last term of equation (2) relating to
sigma has been corrected.
Wall-functions are applied in this implementation by using equations (14)
to specify the near-wall omega as appropriate.
The blending functions (15) and (16) are not currently used because of the
uncertainty in their origin, range of applicability and that is y+ becomes
sufficiently small blending u_tau in this manner clearly becomes nonsense.
The default model coefficients correspond to the following:
\verbatim
kOmegaSSTCoeffs
{
alphaK1 0.85034;
alphaK2 1.0;
alphaOmega1 0.5;
alphaOmega2 0.85616;
Prt 1.0; // only for compressible
beta1 0.075;
beta2 0.0828;
betaStar 0.09;
gamma1 0.5532;
gamma2 0.4403;
a1 0.31;
b1 1.0;
c1 10.0;
F3 no;
Cmub 0.6;
}
\endverbatim
