The MUSIG model tracks a dispersed phase that is represented by a set of size groups. Each size group represents bubbles of a particular diameter. MUSIG models changes in the size of each group due to:
Coalescence and breakup
Thermal phase change

The Polydispersed (MUSIG) model has two variants:
Homogeneous MUSIG
All size groups for a given polydispersed (MUSIG) fluid move according to the same velocity field.
Inhomogeneous MUSIG
The size groups for a given polydispersed (MUSIG) fluid are arranged into multiple velocity groups, with each velocity group associated with a velocity field.
For details on the Polydispersed (MUSIG) model, see Multiple Size Group (MUSIG) Model in the CFX-Solver Theory Guide.
