A Parametric Study on Deoiling Hydrocyclones Flow Field

Authors: Reza Maddahian, Bijan Farhanieh, Maysam Saidi

Abstract:

Hydrocyclones flow field study is conducted by performing a parametric study. Effect of cone angle on deoiling hydrocyclones flow behaviour is studied in this research. Flow field of hydrocyclone is obtained by three-dimensional simulations with OpenFOAM code. Because of anisotropic behaviour of flow inside hydrocyclones LES is a suitable method to predict the flow field since it resolves large scales and model isotropic small scales. Large eddy simulation is used to predict the flow behavior of three different cone angles. Differences in tangential velocity and pressure distribution are reported in some figures.

Keywords: large eddy simulation, flow field, pressure distribution, Deoiling hydrocyclones, Hydrocyclone cone angle
