High Concentration Fine Particle Separation Performance in Hydrocyclones

The vast majority of current research on hydrocyclone field centrifugal separation focuses low concentration fluids having volume fraction less than 3%. For high-concentration fractions greater 10%, which are often encountered in engineering, the law governing particle motion and classification mechanism still unclear. In order to gain insights into interaction between fine particles high improve performance these particles, a Dense Discrete Phase Model (DDPM) Euler-Eulerian method under Ansys Fluent 14.5 software was employed. Numerical simulations were carried out study characteristics dense influence parameters, such as diameter overflow outlet, underflow material concentration, performance. trajectories efficiencies two kinds with different densities six sizes at obtained. results show that for large density small size more likely enter internal cyclone discharge from overflow. Particles external underflow. this topic could provide feasible reference theoretical basis fluid.
