public EddyViscosity (Class EddyViscosity)

Class Documentation

class VanDriestEddyViscosity : public EddyViscosity 

A mixing-length based eddy viscosity model using a van Driest damping function. Corresponds to the formulation used by Cabot in [Cabot].

\[ \nu_t = \kappa u_\tau y (1 - \exp(- y^+/A^+))^2 \]

Usage:

    EddyViscosity
    {
        type      VanDriest;
        APlus     value; (default 18)
        kappa     value; (default 0.4)
    }
