Degreasing Type Hydrocyclone Numerical Calculation Of The Internal Flow Field

In spite of its simplicity in construction, the fluid flow in the hydrocyclone is strongly swirling turbulent flow. Traditional turbulence models are unsuitable. The flow field and pressure drops in the hydrocyclone were calculated numerically based on the k- e model modified for anisotropy and SIMPLE algorithm. The effects of operating parameters such as split ratio and feed flowrate on pressure drop were analyzed. The calculate results was compared with those obtained in experiment. It was found that the calculation result was acceptable.In addition, the trajectories of oil droplets entering the hydrocyclone were computed by using the Particle Obit model. Thereby the separation efficiency of the hydrocyclone can be obtained. The effects of operating parameters such as split ratio and feed flowrate on separation efficiency were analyzed.
