Low Reynolds number kOmegaSST turbulence model for OpenFOAM v4.x.

This code was originally written by RodgriguezFatz from the cfd-online forums. See the original thread at http://www.cfd-online.com/Forums/openfoam-programming-development/134102-komegasst-lowre-damping-fluent.html

Clone this repository into your OpenFOAM user directory and compile with wmake:

cd $WM_PROJECT_USER_DIR
git clone https://github.com/petebachant/kOmegaSSTLowRe.git
cd kOmegaSSTLowRe
wmake libso

In system/controlDict:

libs
(
    "libmyIncompressibleRASModels.so"
);

In constant/turbulenceProperties set

simulationType RAS;

RAS
{
    RASModel        kOmegaSSTLowRe;
    turbulence      on;
    printCoeffs     on;
}

The current implementation only supports incompressible flow since no correction was applied to the original coded k and omega equations. This is due to the way phi_ is calculated:

	const surfaceScalarField& phi_ = this->alphaRhoPhi_;

The model equations can be extended to a compressible formulation, although it requires rewriting the equations for k and omega, and the model might become invalid.
