Detailed Description

Low Reynolds-number k-kl-omega turbulence model for incompressible flows.

This turbulence model is described in:

    Walters, D. K., & Cokljat, D. (2008).
    A three-equation eddy-viscosity model for Reynolds-averaged
    Navier–Stokes simulations of transitional flow.
    Journal of Fluids Engineering, 130(12), 121401.

corrected according to:

    Furst, J. (2013).
    Numerical simulation of transitional flows with laminar kinetic energy.
    Engineering Mechanics, 20(5), 379-388.

and includes the improvements proposed in:

    Lopez, M., and Keith Walters, D. (2016).
    A Recommended Correction to the kT−kL−ω Transition-Sensitive
    Eddy-Viscosity Model.
    Journal of Fluids Engineering, 139(2), 024501.
