Modeling of Separation in a Cocurrent Cylindrical Hydrocyclone

The radial motion of the dispersed phase in a cocurrent cylindrical hydrocyclone under the action of deterministic forces, including the inertial force, is considered. It is shown that the acceleration of particles in the direction away from the apparatus axis toward the apparatus wall can be neglected. Under this assumption, a method is proposed to calculate the characteristics of separation of the solid–liquid and solid–liquid–gas systems.

Transitional modes and crisis phenomena in hydrocyclones

Transitional modes and crisis phenomena caused by the specific features of the velocity field of swirl flows and the dispersed phase in hydrocyclones are studied. The critical situations are analyzed and the reasons for the ambiguity of operational modes and the emergence of crises are discussed.

Computer analysis of the effect of structural and regime operating parameters of a vortical ejector on the coefficient of injection

The influence exerted by structural and regime parameters of a vortical ejector on the coefficient of injection is investigated. A mathematical equation is derived for calculation of the coefficient of injection. Practical use of the equation derived is confirmed by comparing computed and experiment data obtained during investigation of a laboratory prototype of vortical ejector.
