Class
Foam::diameterModels::IATE
Description
IATE (Interfacial Area Transport Equation) bubble diameter model.
Solves for the interfacial curvature per unit volume of the phase rather
than interfacial area per unit volume to avoid stability issues relating to
the consistency requirements between the phase fraction and interfacial area
per unit volume. In every other respect this model is as presented in the
paper:
