public EddyViscosity (Class EddyViscosity)

Class Documentation

class DupratEddyViscosity : public EddyViscosity 

Eddy viscosity model based on the work of Duprat et al. [Duprat].

\[ \nu_t = \nu \kappa y^* [\alpha + y^*(1 - \alpha)^{3/2}]^\beta (1 - \exp(-y^* /(1 + A \alpha^3)))^2 \]

Usage:

    EddyViscosity
    {
        type      Duprat;
        APlus     value; (default 18)
        beta      value; (default 0.78)
        kappa     value; (default 0.4)
    }
