(ASK) Horizontal Primary Separator (gas-oil-water)
dear CFD forum,
i want to modelling horizontal primary separator (gas-oil-water) using FLUENT, http://imageshack.us/photo/my-images/607/separator.jpg/ here is my simulation set up: Boundary condition : inlet (mass flow inlet) outlet (outflow) multiphase model : VOF implict scheme working fluids : gas ----as primary phase oil ----as secondary phase water--as secondary phase viscous model : K-epsilon standard wall function, i did the simulation in unsteady twice but it seems no clearly interface between the phase and the contour of volume fraction seems unreal, did i make some mistakes in here??should i use UDF for this kind of simulation??? |
