I'm modeling two liquids that flow over a rotating disk. this two liquids have same density and viscosity properties. Solver is unsteady, segregated and pressure baser navier-stokes. I'm using multiphase model . Two liquids is supplied the center of the disk.

Any ideas for solving this problem?

in multiphase, we have any models : mixture model, two fluids model...

wat bout using Eulerian model?

see help in fluent off eulerian model, you have all of équation used by this model
