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:
