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