Detailed Description

template<class MomentumTransportModel, class BasicMomentumTransportModel>
class Foam::kOmegaSST< MomentumTransportModel, BasicMomentumTransportModel >

Implementation of the k-omega-SST turbulence model for incompressible and compressible flows.

Turbulence model described in:

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

with updated coefficients from

    Menter, F. R., Kuntz, M., and Langtry, R. (2003).
    Ten Years of Industrial Experience with the SST Turbulence Model.
    Turbulence, Heat and Mass Transfer 4, ed: K. Hanjalic, Y. Nagano,
    & M. Tummers, Begell House, Inc., 625 - 632.

but with the consistent production terms from the 2001 paper as form in the 2003 paper is a typo, see

    http://turbmodels.larc.nasa.gov/sst.html

and the addition of the optional F3 term for rough walls from

    Hellsten, A. (1998).
    "Some Improvements in Menter’s k-omega-SST turbulence model"
    29th AIAA Fluid Dynamics Conference, AIAA-98-2554.

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 if y+ becomes sufficiently small blending u_tau in this manner clearly becomes nonsense.

The default model coefficients are

    kOmegaSSTCoeffs
    {
        alphaK1     0.85;
        alphaK2     1.0;
        alphaOmega1 0.5;
        alphaOmega2 0.856;
        beta1       0.075;
        beta2       0.0828;
        betaStar    0.09;
        gamma1      5/9;
        gamma2      0.44;
        a1          0.31;
        b1          1.0;
        c1          10.0;
        F3          no;
