Modeling particles in air flowing through a pipe FLUENT
 

hey!
Can any one tell me how can i model multiphase flow aluminium/any metal particles flowing through a pipe in Fluents by using eluer-euler approach?
say volume fraction of metal is 0.2. both air and particles entering in domain from pressure inlet at the same time.
I m confused about this should i use Mixture modle, VOF, Euler, or wet stream?
