Separating two different gas
 

Hi,
I want to separate two different gases with different density, should I use mixture or Eulerian model in multiphase tool bar ?

Are the gases miscible? Meaning: you're sure they will stratify/separate? If so, you can use the mixture model as a simplification to the full Eulerian model. If you're trying to model the two fluids in non-equilibrium over small distances (thermal), I believe you'll have to use the Eulerian model.

See this link for limitations of the mixture model: http://my.fit.edu/itresources/manual...ug/node891.htm
