Fluid dynamics in ansys-fluent 14 environment.The hydrocyclone swirling flow was simulated using rng swirl dominated k- turbulence model while the interface between crude oil and water was achieved using the discrete phase model.Based on the simulation results, it is concluded that hydrocyclone separation efficiency is affected by inlet.
Ansys fluent provides the flexibility for the fluid flow time step size to be a different value and hence we almost always choose a higher value to speed-up the simulation, said gohel.The dense discrete phase model dense dpm is the final one used to simulate the system.

However, the separation efficiency could be reduced due to the limitations of inlet width and capacity in this case.A novel impeller hydrocyclone is designed to solve this problem, and the influences of impeller on inner fluid flow rate have been discussed by simulating fluid flow patterns using a common cfd software, fluent.
You can use fluent to predict the discrete phase patterns based on a xed continuous phase ow eld an uncoupled approach, or you can include the e ect of the discrete phase on the continuum a coupled approach.In the coupled approach, the continuous phase ow pattern is impacted by the discrete phase and vice versa, and you can alternate.
