Analysis of internal flow field performance of hydrocyclone based on CFD

This paper uses CFD software ANSYS Fluent, based on RSM Reynolds stress model and VOF two-phase flow model, to calculate the turbulent field inside ∅75mm heavy dispersed phase particle separation cyclone. Combined with experimental working parameters under different inlet pressures, results were compared. Check accuracy of formula calculation numerical simulation results. The show that air column cyclone is stable internal pressure gradient continuous Well, axial tangential velocity fields are consistent reality. Compared empirical formula, fluent can more accurately predict processing capacity hydrocyclone, classification efficiency obtained close value.
