|Summary||0000286: kOmegaSST model wrong implementation of the production term|
|Description||The production term in the omega equation is wrongly implemented (as of the version 2003, by Menter). The implementation reads |
for the incompressible version of the model, but should be
where G is then Pk in the paper. The paper was subsequently corrected (see SST-2003 on http://turbmodels.larc.nasa.gov/sst.html ), and the term is still the same in the OF model. It is described as a typographical error for the paper.

I can not see the discrepancy between your reference (http://turbmodels.larc.nasa.gov/sst.html) and
the reference stated on the header file of the model
(Menter, F., Esch, T.
"Elements of Industrial Heat Transfer Prediction"
16th Brazilian Congress of Mechanical Engineering (COBEM),
regarding the production term of the Omega Eq.
I'd need further clarification.

The discrepancy is described under "Menter SST Two-Equation Model from 2003 (SST-2003)" on the website, where they state that the production term has changed.
But I must have read the year wrong in the header file. Since I don't have the paper at hand, I can't double check this. Except for the production term, everything is the same. Either the model from 2003 is a corrected model (compared to 2001) or an alternative new model, with a different source term (equation (1) in Menter, F. R., Kuntz, M., and Langtry, R., "Ten Years of Industrial Experience with the SST Turbulence Model," Turbulence, Heat and Mass Transfer 4, ed: K. Hanjalic, Y. Nagano, and M. Tummers, Begell House, Inc., 2003, pp. 625 - 632. )
