public ExplicitLawOfTheWall (Class ExplicitLawOfTheWall)

Class Documentation

class CaiSagautExplicitLawOfTheWall : public ExplicitLawOfTheWall 

The explicit law of the wall proposed by Cai and Sagaut. This is “model 2” in the paper. Uses the Lmabert W function to explicitly represent the log-law.

\[ u^+ = \exp(-Re_y / s)^p \sqrt(Re_y) + (1 - \exp(-Re_y /s))^p W(Re_y \kappa E) / \kappa \]

Usage:

    Law
    {
        type      CaiSagaut;
        kappa     value; (default 0.4)
        B         value; (default 5.5)
        p         value; (default 1.138)
        s         value; (default 217.8)
    }
