Impact of bubble coalescence on separation performance

25/09/2015  The separation efficiency for 30-μm bubbles increases from 29.67% to 99.53% when the bubble diameter changes from 30 μm to 100 μm. The gas concentration changes more quickly at the center of the hydrocyclone, while the range of bubble sizes that coalesced increases. The break-up and coalescence of larger bubbles lead to a pressure increase ...

Hydrocyclone - Wikipedia

A hydrocyclone (often referred to by the shortened form hydroclone or cyclone) is a device to classify, separate or sort particles in a liquid suspension based on the ratio of their centripetal force to fluid resistance. This ratio is high for dense (where separation by density is required) and coarse (where separation by size is required) particles, and low for light and fine particles. Hydrocyclones also find application in the separation of liquids of different densities.

The maximum bubble diameter is one of the most important factors affecting bubble separation in a hydrocyclone and is essential to the analysis and design of a degassing hydrocyclone.

Bubble‐separation dynamics in a planar cyclone ...

A planar cyclone is designed for visualizing bubbles in the cross‐section of a degassing hydrocyclone. The pressure distribution is studied through a series of experiments and Reynolds stress model simulations. The velocity distribution of the planar cyclone mostly exhibits the quasi‐forced vortex zone and boundary layer zone. The bubble dynamics are simulated using both Euler‐Euler and
