flow in hydrocyclone mode

Hydrocyclone Wikipedia

Generally, hydrocyclones are used in continuous flow systems so that the instantaneous liquid inflow to the hydrocyclone is equal to the total instantaneous outflow of "lights" plus "heavies". In cases where "heavies" are a very small part of the whole liquid, it is sometimes advantageous to accumulate them in the bottom of the hydrocyclone for batchwise removal.

Numerical analysis of hydroabrasion in a hydrocyclone .

In this approach, the abrasive solid particles were traced in a Lagrangian reference frame as discrete particles. The increases in the input flow velocity, solid concentration, and the particle size have increased the erosion at the upper part of the cylindrical body of the hydrocyclone, where the tangential inlet flow enters the hydrocyclone.

CYCLONES 5555 HydroCyclones A typical hydrocyclone consists of a conically shaped vessel, open at its apex (spigot), or underflow, joined to a cylindrical section, which has a tangential feed inlet. The top of the cylindrical section is closed with a plate through which passes an axially mounted overflow pipe.

The Effect of Inlet Velocity on the Separation Performance .

To study multiphase flow in a hydrocyclone, the VOF model is widely adopted to investigate the air core inside a hydrocyclone. A particle image velocimetry (PIV) test and other flow field tests verified that the VOF model can accurately predict the distribution characteristics of the gasliquid twophase flow in the hydrocyclones [ 35 ].

Experimental study of flow patterns in deoiling hydrocyclone

Using a twocomponent laser Doppler velocimeter, the axial velocity, tangential velocity and fluctuation velocity were measured in a 35mm deoiling hydrocyclone. Air core occurs in the hydrocyclone when inlet flow rate is more than 2.00 m 3 /h. The fluctuation velocities with air core are greater than without air core.

Hydrocyclone Working Principle

Hydrocyclone Working Principle. Unlike the rake and spiral classifiers, the overflow of the cyclone is the exit point for the fine material instead of the other way around as it is in the case of the other two. Extending from the overflow discharge into the body, which is the feed entry point of the cyclone, is the VORTEX FINDER.
