Lien and Kalitzin's v2-f turbulence model for incompressible and compressible flows, with a limit imposed on the turbulent viscosity given by Davidson et al.
The model solves for turbulence kinetic energy k and turbulence dissipation rate epsilon, with additional equations for the turbulence stress normal to streamlines, v2, and elliptic damping function, f.
The variant implemented employs N=6, such that f=0 on walls.
Wall boundary conditions are:
k = kLowReWallFunction epsilon = epsilonWallFunction v2 = v2WallFunction f = fWallFunction
These are applicable to both low- and high-Reynolds number flows.
Inlet values can be approximated by:
v2 = 2/3 k f = zero-gradient
