The Effect of Fluid Viscosity on Hydrocyclone . BORA UiB

velocity profiles in a hydrocyclone is only qualitative. The flow patterns in a hydrocyclone are highly complex, and it may be incorrect to assume that precisely similar profiles occur in cyclones with a considerably different geometry or for liquids of high viscosity. 2.3.1 Tangential Velocity.

Particles Separation and Tracks in a Hydrocyclone

The air core in hydrocyclone will arise turbulence fluctuation, and decrease separation efficiency [9]. The velocity profiles of hydrocyclones were first measured by Kelsall [10], he found that the tangential velocity increased to a maximum from hydrocyclone wall towards the center, and then decreased rapidly.

Fondamental understanding of swirling flow pattern in hydrocyclones

The work finds velocity profiles to be the most discriminating parameter for validation of the physics that describes the swirling flow inside the hydro cyclone. Water split on the other hand shows no relation to the choice of turbulence model and hence cannot be used to validate a mechanistic model of the hydrocyclone.

Since the tangential inlet imposes a strong rotational movement in the hydrocyclone interior, generating a symmetry in the velocity field, thus, the velocity can be considered independent of the polar angle in . Thus, the distribution of the turbulent viscosity on the field of the low should be determined by the turbulence model.
