Detailed Description

Lien and Leschziner low-Reynolds number k-epsilon turbulence model for incompressible flows.

This turbulence model is described in:

    Lien, F. S., & Leschziner, M. A. (1993).
    A pressure-velocity solution strategy for compressible flow
    and its application to shock/boundary-layer interaction
    using second-moment turbulence closure.
    Journal of fluids engineering, 115(4), 717-725.

Implemented according to the specification in: Apsley: Turbulence Models 2002

In addition to the low-Reynolds number damping functions support for wall-functions is also included to allow for low- and high-Reynolds number operation.
