A revised approach to modelling turbulent flow in small-diameter (10–44 mm) hydrocyclones is presented and tested quantitatively against experimental measurements. Some of the limitations inherent in the existing approaches, such as the anisotropy of turbulent viscosity and the non-linear interaction between mean vorticity Empirical models are now used for predicting the performance of hydrocyclones in terms of capacity, cut size (d50,c), water split and partition curve. These models (such as the model by Lynch and Rao and the model by Plitt) were developed and checked for hydrocyclones with diameters larger than 4 in. However, for smaller Small-diameter hydrocyclones: Performance prediction by empirical

A series of small diameter hydrocyclone experiments illustrate the use of the model and are used to evaluate the bypass. It is often assumed that the bypass can be estimated accurately from the fraction of water in the feed that reports to The main parameter of a hydrocyclone is its diameter, i.e., the inside diameter of the cylindrical feed chamber. Even so, the potential of very small diameter hydrocyclones in the classification of submicron size particles would be large, if these problems can be solved (Cilliers, 2000).Hydrocyclones ScienceDirect

In this study, the effect of cone ratio (ratio of the vortex finder diameter to the apex diameter, D o /D u) on by-pass was investigated for small diameter hydrocyclones.Experimental studies were carried out in a closed circuit laboratory test rig for a wide range of operational parameters, such as diameter of cyclone, vortex finder The application of small hydrocyclones for dewatering fine particles in bioprocesses is of growing interest [1], [2], [3], [4].Since the diameter of the hydrocyclone determines largely the particle cut-size achieved [5], small diameter hydrocyclones can be used for particle separation in the micron range.

For small-diameter hydrocyclones, such as the 10-mm size (Cullivan et al., 2003), the flow split could be predicted without regard for the accuracy of the air-core prediction. However, as the hydrocyclone diameter increases, the available open area for flow increases the flow through the outlets. In this work, we attempt to predictFig. 1 shows the geometry of the mini-hydrocyclone and Table 1 lists the corresponding geometric values. The diameter of the mini-hydrocyclone is 10 mm. The diameter of the mini-hydrocyclone is 10 mm.

The small diameter of a hydrocyclone enables improved separation accuracy, and its series–parallel connection makes it suitable for high-throughput or low-concentration cases [27]. The adjustment system controls the work in the high efficiency zone. Show abstract.These results contrast with the models usually used in small diameter hydrocyclones.
