The search continues for accurate and efficient 3D computational fluid dynamics algorithms for hydrocyclone flows. A review of
recent work and new developments are presented. This contribution is based on the authors’ past experience both in creating their
own specialized numerical approaches and using commercial packages for simulating swirling flow. In particular, the paper presents
the application of the developed 3D finite element code to hydrocyclone modelling. Some important factors in the numerical
solution of the model equations, namely proper representation of geometry, imposition of boundary conditions and the choice of
turbulence model, are discussed. Numerical results indicate the versatility and the effectiveness of the new approaches. A scheme that
utilizes numerical results in the multi-objective design is also suggested. Remaining technical difficulties are highlighted in order to
suggest key directions for future work.
