Numerical investigation of the hydrocyclone vortex finder depth on separation efficiency

Hydrocyclones are devices used in numerous chemicals, food, and mineral-related industrial sectors for the separation of fine particles. A d50 mm hydrocyclone was modelled with use Computational fluid dynamics (CFD) simulation, ANSYS® Fluent 2021 R1. The vortex finder depth varied from 20 mm, 30 35 to observe effects pressure drop efficiency a characteristics air core. numerical methods validated results observed different parameters such as volume fraction based on CFD simulations. tangential axial velocities increased length increased. It found that is increased, particle re-entrainment time underflow stream increases, improved.
