Number of Interfaces in 3D Multiphase flow
 

Hi,
In 3 Dimensional Eulerian Multiphase flow what is the effect of giving more that one interface? For Momemtum and Energy interfacial exchange, Does putting more than one interface helps ?

Please give some idea of the number of interace in a complex geometry.

Can anyone please help me in this regard ??

Cheers,
Nazz.
