Regarding volume fraction discretization scheme in Eulerian Multiphase flow model (Two-fluid model)?

  How sensitive are volume fraction discretization schemes such as first-order upwind, Modified HRIC, compressive, etc. in Eulerian Multiphase flow simulations?
  Any drastic change in results can come with these different schemes?

  Sure you would expect a change but all three schemes (even QUICK and HRIC) are diffusive enough so that the overall behavior won't drastically change.
