Has anyone implemented any zero equation turbulence models to OpenFOAM? That is, a turbulence model which uses algebraic equations to calculate turbulent viscosity rather than PDE's (k, ε etc.). The classic example of this is the Prandtl mixing length model.

I'm trying to implement a specialized model and am having trouble modifying the 2 and 1 eq models to remove the PDE's, so I figured having a zero equation model already implemented would help me understand what I need to do.

Thanks
