Detailed Description

Solving the void fraction $ \alpha $ for the Volume of Fluid method (and hence for cavitating flows).

This function solves the equation:

\[ \dfrac{\alpha^n - \alpha^{n-1}}{\Delta t} + \divs \left( \alpha^n \vect{u}^n \right) + \divs \left( \left[ \alpha^n \left( 1 - \alpha^{n} \right) \right] \vect{u^r}^n \right) = \dfrac{\Gamma_V \left( \alpha^{n-1}, p^n \right)}{\rho_v} \]

with $ \Gamma_V $ the eventual vaporization source term (Merkle model) in case the cavitation model is enabled, $ \rho_v $ the reference gas density and $ \vect{u^r} $ the drift velocity for the compressed interface.
