EffectiveVolume

Source: models/chemical_reactions/EffectiveVolume.py

Total volume of a control-mass composite during a reaction.

\[ V = \frac{M}{1 - \phi_o} \sum_i \frac{\omega_i}{\rho_i} \]

where \(\omega_i\) and \(\rho_i\) are the mass fraction and density of each component, \(\phi_o\) is the open volume fraction (accounting for leakage out of the control mass), and \(M\) is the reference mass of the composite. The open-volume-fraction input is optional - when HIT is silent the prefactor reduces to \(M\).
