The use of 3D to manufacture small hydrocyclones of various designs has been proven in this study to be practical and to allow rapid prototyping design informed by CFD simulations.

Hydrocyclones are cyclones specially designed for liquids in which the basic separation principle employed is centrifugal sedimentation, i.e. the suspended particles are subjected to a centrifugal acceleration that separates them from the fluid [9]. The hydrocyclone conventional design consists of a cylindrical section joined to a conical …

Therefore, for a reliable design of hydrocyclones, the change of discrete-phase distribution in flow field of hydrocyclones, that is, the droplet coalescence and/or breakup (Fig. 3), has to be considered [103]; and further research has to been carried out systematically to investigate the occurrence condition of discrete-phase breakup and ...

All hydrocyclones are composed of four (4) main sections: 1. Inlet The inlet section is comprised of a cylindrical feed chamber which serves to convert the incoming flow to a tangential flow with minimal turbulence. Critical design variables include the inlet area and inlet type. Smaller inlet sizes result in increased tangential velocity at the

Finally, numerical modelling of hydrocyclones continues to advance strongly on the back of concomitant improvements in computer technology, software, and increasing insight into flow processes in hydrocyclones. This will lead to improvement in hydrocyclone design and will extend their range and flexibility even further.

Hydrocyclone Working Principle. The centre of this spiral is called the VORTEX. The purpose of the apex is to cause internal pressure for the cyclone and to create a vortex that extends all of the way to the top of the cyclone. In all hydrocyclones there are two outlets, one for the coarse material, this is the APEX, and the other for the …

Design Considerations. Hydrocyclones are 20-500 mm in diameter, with the smaller units giving a much better separation. Typical values of length to diameter ratios range from about 5 to 20. Because of the very high shearing stresses which are set up, flocs will be broken down and the suspension in the secondary vortex will be completely ...

Hence, optimizing the design of the hydrocyclone is of great significance for improving the separation performance. According to its structure, hydrocyclones can be divided into the cylindrical-conical type and cylindrical type. Due to the difference in structure, the cylindrical-conical type has higher separation accuracy and lower cut size ...
