This simple model generates a phase change between two phases calculated
from the following expression:
\dot{m}/V = C \alpha \grad \alpha
Where:
\dot{m}/V | mass transfer rate per unit volume
C | coefficient
\alpha | volume fraction of the source phase
Example usage:
coefficientPhaseChange
{
type coefficientPhaseChange;
phases (liquid vapour);
C [kg/m^2/s] 0.1;
}
This model may be of use in simple situations, but it is primarily
designed to serve as a prototype for more complex and physical
mechanisms of phase changes.
