Study of the Fluid Passing through the Screen in the Three Products Hydrocyclone Screen (TPHS): A Theoretical Analysis and Numerical Simulation

The three products hydrocyclone screen (TPHS), a branch of the hydrocyclone, effectively removes fish-hook effect, which has been used in industrial field. current cylindrical TPHS generates characteristic flow known as underflow, significant impact on device performance. To investigate behaviour fluid passing through screen, combination dynamic analysis and numerical simulation was used. permeating process abstracted by simple fan mode this work to generate flow-rate equations driving-force models. pressure difference driving force for penetration ideal fluid, but it also included viscous fluid. Furthermore, at same inlet velocity, had higher rate than ideal, indicating that viscosity promoted penetration. Meanwhile, velocity increased, mass backflow while corresponding proportion first rose peak then dropped gradually stabilised. equation underflow developed, is related structural parameters (the rotation radius, length aperture size, open-area percentage) between feed outlet).
