what does "multiphase" mean?
 

The mixture model is designed for two or MORE phases (fluid or particulate)". In addition, in Panel "Models > Multiphase... >", I can define Number of phases up to 20. Does that mean Fluent can model a multiphase ( >2 phases) flow?

What does multiphase (say 10 phases) mean?

Thank you a lot!

Yes, FLUENT can model a flow up to 20 phases.

A phase can be defined as a portion of your system which is physically and chemically homogeneous (see a book of Physical Chemistry for a better definition).

Gas-liquid-solid flows, as water-air-sand, are examples of three-phase systems.

Not miscible fluids are another example of multiphase flow (ex: water, air, oil).

Multiphase (>2) systems are also over-saturated solutions of salts.

A higher (>2) number of phases can be used, for example, in granular flows, to account particle size distribution, considering all particles of a given size as a single phase.
