epsilonWallFunction: Expression of espilon in log layer

In this documentation page about epsilonWallFunction, the expression of \epsilon_\text{log} is given by:

\epsilon_\text{log} = wC_\mu\frac{k^{3/2}}{\nu_{t,w}y} \tag{1}

However, in the source code, the following expression is used:

\epsilon_\text{log} = wC_{\mu}^{3/4}\frac{k^{3/2}}{\kappa y} \tag{2}

Unless the expressions \frac{C_\mu}{\nu_{t,w}} and \frac{C_{\mu}^{3/4}}{\kappa} are equivalent, the expression (1) should be corrected in the documentation.

Thank you
