Lien cubic non-linear low-Reynolds k-epsilon turbulence models for incompressible flows.
This turbulence model is described in:
Lien, F.S., Chen, W.L. & Leschziner, M.A. (1996). Low-Reynolds-number eddy-viscosity modeling based on non-linear stress-strain/vorticity relations. Engineering Turbulence Modelling and Experiments 3, 91-100.
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.
