class IntegratedReichardtLawOfTheWall : public LawOfTheWall

Model based on integrating the law of the wall proposed by Reichardt.

\[ u^+ = \frac{1}{\kappa } \ln (1 + \kappa y^+) + C \left( 1 - \exp (-y^+/B_1)- \frac{y^+}{B_1} \exp(-y^+/B_2) \right) \]

Usage: 

    Law
    {
        type      IntegratedReichardt;
        kappa     value; (default 0.4)
        B1        value; (default 11)
        B2        value; (default 3)
        C         value; (default 7.8)
    }
