the basic features of the hydrocyclone flow field

MOSFET Wikipedia

The basic principle of the field-effect transistor (FET) was first proposed by Austrian physicist Julius Edgar Lilienfeld in 1926, when he filed the first patent for an insulated-gate field-effect transistor. Over the course of next two years he described various FET structures. In his MOS configuration aluminum stood for M, aluminum oxide stood for O, while copper sulfide was used as a

Numerical studies of hydrocyclones effectively started in the 1980s to predict the flow field with considerably more accuracy and beyond the capabilities of any possible analytical solution. The first successful numerical simulation of the flow in hydrocyclones was described in a series of papers by Pericleous and Rhodes (1984, 1986 and 1987).

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.
