Designing automated computational fluid dynamics modelling tools for hydrocyclone design
T. J. Olson and R. Van Ommen, “Optimizing hydrocyclone design using advanced CFD model,” Minerals Engineering, vol. 17, no. 5, pp. 713–720, May 2004, doi: 10.1016/j.mineng.2003.12.008.
Abstract: 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.
Until 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.
This paper 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.

A simple procedure for design and performance prediction of Bradley and Rietema hydrocyclones
L. R. Castilho and R. A. Medronho, “A simple procedure for design and performance prediction of Bradley and Rietema hydrocyclones,” Minerals Engineering, vol. 13, no. 2, pp. 183–191, Feb. 2000, doi: 10.1016/S0892-6875(99)00164-8.
Abstract Hydrocyclones were originally designed to promote solid-liquid separations but nowadays they are also used for solid-solid, liquid-liquid and gas-liquid separations. Although a hydrocyclone is a very simple equipment to build, the use of custom-made cyclones is not widely used. This is probably due to the lack of a simple procedure for hydrocyclone design. In the present work a procedure is presented, which allows the design and performance prediction of hydrocyclones that follow Bradley and Rietema recommended geometries, that are the only two well-known families of geometrically similar hydrocyclones. The procedure proposed here resulted in little error, when the results were compared with experimental data. Additionally, a comparison of both families of hydrocyclones revealed that, for a given hydrocyclone diameter and at the same operational conditions, Bradley hydrocyclones provide higher efficiencies, while Rietema hydrocyclones give higher capacities.

Abstract Hydrocyclones belong to an important group of equipments designed to solid–liquid or liquid–liquid separation in a centrifugal field. It is possible to adapt a hydrocyclone to the accomplishment of several industrial activities depending on the geometrical relations among its main dimensions. The operation and design of these devices are relatively simple; however, the flow inside them is very complex and its prediction is very difficult. For that reason, most models that are used to predict hydrocyclone performance are empirical ones. The objective of this work was to study the influence of geometric variables in the performance of hydrocyclones, using CFD and response surface techniques. The obtained results show that it was possible to find an optimum hydrocyclone design, that is, geometric relationships that lead to Euler number and cut size in minimum levels.
