Effect of Inlet Cylindrical Section on Dewatering Hydrocyclone Performance by CFD Simulation

In this work, a Colman-Thew hydrocyclone type has been simulated utilizing CFD method. In order to take into account the turbulent and multi-phase flow RSM approach and Eulerian-Eulerian model has been applied, respectively. Moreover, for verification obtained results, a comparison between results and reported experimental data are drawn in term of hydrocyclone separation efficiency and split ratio. These results show 9% and 7% average errors for separation efficiency and split ratio respectively. Furthermore, the results show that by decreasing the length of the cylindrical section of hydrocyclone from h=1.5D to h=0.29D, efficiency and overall efficiency incrase 20% and conic shape instaed of cylindrical section, improves the hydrocyclone performance 10%.
