I am simulating water flow boiling through rectangular microchannel using Multiphase VOF model (evaporation-Condensation Mechanism)

 

Why we have to take number of eulerian phases =3

i.e. Air as Primary phase, Liquid water and Liquid Vapor as Secondary phases.

 

Can't we take 2 i.e. Water-Liquid as 'Primary Phase' and Water-Vapor as ' Secondary Phase' (as I see no boiling with 2 phases)

 

Please guide

 

Thanks in advance

You have two phases, of which the vapour phase contains two species.
