Open Fuel Cycle
Once-through Fuel Cycle. An open fuel cycle is not a real cycle. This strategy assumes that the fuel is used once and sent to long-term storage without further reprocessing. If spent fuel is not reprocessed, the fuel cycle is referred to as an open fuel cycle or a once-through fuel cycle, as the uranium components go through the reactor once ...

Flow Pattern in Hydrocyclones | SpringerLink
Since the flow enters at the periphery and top of the hydrocyclone and leaves through the top and the bottom of the vessel at its center, there is a three-dimensional fluid motion, called vortex motion, with tangential, axial and radial velocities.The vortex motion produces a low-pressure zone in the center of the device …

Air core formation in the hydrocyclone
Air flow through the hydrocyclone. Fig. 1 presents schematically the air balance of the hydrocyclone. Generally, two ways of air input can be distinguished. In dilute flow separation (spray discharge in the underflow) air is sucked through the spigot to the centre of the hydrocyclone. However, also feed suspension always contains a …

Hydrocyclone Working Principle
Hydrocyclone Working Principle. The centre of this spiral is called the VORTEX. The purpose of the apex is to cause internal pressure for the cyclone and to create a vortex that extends all of the way to the top of the cyclone. In all hydrocyclones there are two outlets, one for the coarse material, this is the APEX, and the other for the …

Three-phase hydrocyclone separator – A review
From the beginning of 1990s, different types of three-phase hydrocyclone have been developed with little application and research. Through a brief introduction of three-phase hydrocyclone type and present technical situation, this paper analyzed the deficiencies of different three-phase hydrocyclone and came up with suggestions for …

(PDF) The Effect of Feed Solids Concentration on Hydrocyclone
As there is no entrainment of air through the outlets, the air core formation was not modelled. The investigation showed that the cut size of axial flow hydrocyclone (d50=20.46 and 20.3 micrometres) was larger than the reverse flow hydrocyclone (d50=17.73 and 17.81 micrometres) at particle concentrations of 4.88% and 10.47%, …

Function and applications of hydrocyclones
The use of a hydrocyclone is an efficient solution to avoid clogging and thus reduce maintenance (compared to traditional cartridge filters) or repair interventions. The Nice-based company Hectron has a range of hydrocyclones that are effective tools for separating sand from water. These devices are widely used in many fields.

Hydrocyclones
In a hydrocyclone, a slurry enters through a tangential inlet, giving rise to a vortex in the stationary body. The particles and fluid are accelerated centrifugally and separation occurs in the radial direction. Denser materials migrate to the outer wall of the hydrocyclone chamber, while less dense materials move toward the inner axis. ...
