subroutine resvoi (dt, iterns)

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.
