class IntegratedWernerWengleLawOfTheWall : public LawOfTheWall 

The integrated version of the wall proposed by Werner and Wengle. Explicitely couples shear stress with the wall-normal-averaged velocity. Derived assuming that the sampling is from the wall-adjacent cell.

Based on the following law of the wall.

\[\begin{split}\begin{eqnarray*} u^+ &=& y^+ \quad y+ \leq 11.81\\ u^+ &=& A(y^+)^B \quad y^+ > 11.81 \end{eqnarray*}\end{split}\]

Usage:

    Law
    {
        type      IntegratedIntegratedWernerWengle;
        A         value; (default 8.3)
        B         value; (default 1/7)
    }
