NUMERICAL STUDY OF LIQUID-SOLID SEPARATION PROCESS INSIDE THE HYDROCYCLONES WHIT DOUBLE CONE SECTIONS

摘要

The major objective of this study was, using the modern numerical techniques, to investigate particle transport processes within a hydrocyclone whit double cone sections, were the wastewater is depurated. This investigation consists of calculations of the fluid flow inside the hydrocyclone, including particle trajectory, pressure losses and separation efficiencies. The hydrocyclone has modeling whit the proper geometrical relationship between the cyclone diameter, inlet area, vortex finder, apex orifice, and sufficient length providing retention time to properly separation particles. Obtained results of calculations were numerically verified as well as compared with results published in the subject literature. The model will predict the velocity particle and fractional recovery of solid particles requirements given the dimensions of the cyclone, the physical properties of the fluid, and the volumetric flow rate.
