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:
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.
Turbulence model described in:
Menter, F., Esch, T.
"Elements of Industrial Heat Transfer Prediction"
16th Brazilian Congress of Mechanical Engineering (COBEM),
Nov. 2001
with the addition of the optional F3 term for rough walls from
Hellsten, A.
"Some Improvements in Menter’s k-omega-SST turbulence model"
29th AIAA Fluid Dynamics Conference,
AIAA-98-2554,
June 1998.
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:
