Abstract

Cyclones are used widely in industry as classifying Devices. Due to the complexity of the multiphase flow field in such a device, prediction methods are at best semiempirical and geared towards predicting overall performance parameters. This article presents a real alternative, using state-of-the-art numerical techniques to address the physics describing the flow and solving the Navier-Stokes equations describing the mixture velocities and the transport equations for air and particle concentrations. Turbulence is modelled in a way that takes into account the effects of swirl and also the presence of particles. An algebraic slip model (ASM) is used to represent the relative migration of particles and air in the liquid mixture. The calculation yields field values of velocity, pressure, particle and air concentrations, as well as the overall performance parameters more familiar to cyclone operators.
