Numerical modelling of an oscillatory baffled column

Abstract

Includes bibliographical references (leaves 53-54).The aim of this project was to develop a numerical model to resolve the flow field in a general OBC. This model can then later be modified to be used to model the more complex aBC that is presently being experimentally tested by the Mineral Processing Research Unit at the University of Cape Town. The commercial CFD code FLUENT 6.2.16 was used to create the modeL Numerical simulations were conducted to investigate the effects of di fferent methods of defining the oscillatory flow, using both RANS turbulence models and Large Eddy Simulation (LES) to model turbulence, as well as different grid sizes and different discretization schemes
