Simulation of Particle Flow in Vortices

Cyclone reactors separate the particles basing on the fluid mechanisms of the particulates in the vortices of the gas or liquid fluid phase, where at high speed rotation air (liquid) flow the larger (denser) particles leave the flow path of the fluid vortices due to the inertial characters of the particulate matters, when finally particles strike on the outer surface of the cyclone reactor the particle separation achieved. To understand the separation mechanism and control the efficiency of the cyclone separator, the two-phase flow, particle flow behavior in vortices, is essential to be investigated. In this article, the fundamental research is going to be presented, comprising the motion mechanisms of the particles with various sizes in air vortices, the agglomeration of fine particles in vortices and also the effect of particle agglomeration on the particle separation.
