ABSTRACT


Hydrocyclone separation technique recently has been used in an increasing number of applications. Reynolds Stress Turbulence Model (RSM) and Discrete Phase Model (DPM) were employed in Computational Fluid Dynamics (CFD) 3D simulation to draw the motion trace of single particle of different particle size and density in hydrocyclone separator. It is known that, smaller size particles flow out from overflow, larger size particles flow out from underflow, and there is a characteristic size of particles having longer residence time in hydrocyclone separator. Particle size influences separation efficiency more significantly than particle density. Simulation of particle cluster separation efficiency in hydrocyclone separator has some discrepancy from experimental result. It is because air core influence is not considered in this study.
