Performance of axial flow hydrocyclones UNSW Canberra

Axial flow hydrocyclones have both exits in the same direction unlike the reverse flow hydrocyclones that are commonly used in industry. Early work has shown that axial flow hydrocyclones can reduce pressure drop and the challenge is to optimise the design of the vortex finder and the outlets to improve the separation efficiency so that the axial flow hydrocyclones can be used to separate a wide range of materials including coal, minerals, and waste effluent.

Performance enhancement of axial concurrent liquid–liquid ...

An axial inlet hydrocyclone operates based on the principle of centrifugal force. The flow is generated axially at the top inlet and passes through the swirl generator to the bottom. The swirl generator placed inside the hydrocyclone body helps generate the swirling flow, which in turn separates fluid mixtures with a dissimilar density.

Their cylindrical top and conical base create a vortex which creates a centrifugal force to separate and classify different sized particles. This vortex forces lighter particles through the top overflow, while denser or larger solid particles pass through the bottom underflow.
