Designing automated computational fluid dynamics modelling tools for hydrocyclone design

Resolution of the complex multiphase swirling flow field in a hydrocyclone using computational fluid modelling techniques is not a trivial task. CFD Modelling technology is not perfect and it is certainly still possible to improve our understanding of the fundamentals and the models needed to describe them. Nevertheless, computational modelling techniques are being used to compare and understand the workings of different hydrocyclone designs and modes of operation. now, CFD has been the realm of the research analyst more than the plant or design engineer. The development of in house CFD expertise may be seen as prohibitive in terms of time and cost. These two factors have presented a barrier to the use of CFD by the hydrocyclone industry, in spite of improvements in modelling capability. aper describes how automated CFD tools have been developed based on documented best practices. The bespoke tool development described will enable a non-CFD analyst to carryout hydrocyclone simulations. The paper will also consider the advantages and limitations of different computational fluid dynamic techniques applicable to hydrocyclone modelling.
