The tangential velocity profile for pseudoplastic power law fluids in a hydrocyclone is determined with an analytical solution to a simplified momentum balance equation by the method of perturbation.

These data were checked for consistency and compared with the results of earlier work in hydrocyclones operating with air cores. The tangential velocity profiles were found to be similar to those produced with an air core although, n. in V A I n = const, is about 0.2 to 0.4 instead of 0.7 to 0.8 for air core operation. In this work the radial velocity component was relatively independent of radius.

Swirling flows in hydrocyclones From experimental works (LDV) we know that the flow in a hydrocyclone (conical and flat bottom) has the following properties velocity profiles of v z and v are not completely axisymmetric v z,v , and their RMS values z and , only change their magnitude with pressure p v z changes with z

The tangential velocity profile for pseudoplastic power law fluids in a hydrocyclone is determined with an analytical solution to a simplified momentum balance equation by the method of perturbation. A numerical solution of the non linear two point boundary value problem by the finite difference method provides a verification of the perturbation solution.

The nondimensional peak tangential velocities are approximately equal for all of the flow rates. The magnitude of the tangential velocity increased in the inner forced vortex region as the rejects rate was increased. Backflows exist in the axial velocity profile near the inlet region, but these reversed flows disappear in the exit region.

The tangential velocity profile for pseudoplastic power law fluids in a hydrocyclone is deter mined with an analytical solution to a simplified momentum balance equation by the method of perturbation.

The hydrocyclone for de oiling of water was developed in 1980 by Colman and Thew. For its performance we base ourselves on an article by Young et al., in which a hydrocyclone with a 35 mm radius, and variants thereof, was tested. Important results of this investigation were the following Flow rate.

application of CFD as a hydrocyclone design tool is also discussed. Physically realistic velocity profile predictions were obtained, which challenge the classical account of the hydrocyclone radial particle classification mechanism. A pressure field distribution consistent

The velocity distribution within the hydrocyclone is impacted by the rate at which the fluid swirls or spirals when it enters the cyclone. Study was done into the velocity profiles that existed in the hydrocyclone types. Figure 5 shows the axial velocity profile in the single and dual 30 mm UCL hydrocyclones taken at different axial locations.

The hydrocyclone is a simple piece of equipment that uses fluid pressure to generate centrifugal force and a flow pattern which can separate particles or droplets from a liquid medium. These particles or droplets must have a sufficiently different density relative to the medium in order to achieve separation.

The tangential velocity flow field in a conical hydrocyclone was measured using a self cleaning pitometer. The influence of pulp fibre concentration on the tangential velocity profile was of particular interest. The measurements showed that the pulp fibres had a strong influence on the tangential velocity profile.
