Asymptotic Properties of a Probabilistic-Statistical Model of Particle Classification in Hydrocyclones

摘要

The peculiarities of practical implementation of a probabilistic-statistical model for a hydrodynamic stage of particle classification process of liquid-solid polydisperse systems in cylinder-conic hydrocyclones of small size have been investigated. Within reasonable assumptions, stationary solutions of the Fokker-Planck-Kolmogorov kinetic equation were obtained for the considered separation process. In order to describe changes in characteristics of suspension separation in hydrocyclones it was proposed to use stationary distributions, which parameters depend not only on hydraulic and dynamic features of flows inside an apparatus, but also are determined by relative magnitudes of the impact of particle classification and centrifugal forces in comparison with the intensity of random perturbations.
