Abstract EN
An estimation of increasing the volume average sedimentation velocity of fine particles in bidisperse suspension due to their capturing in the circulation zone formed in the laminar flow of incompressible viscous fluid around the spherical coarse particle is proposed.
The estimation is important for an explanation of the nonmonotonic shape of the separation curve observed for hydrocyclones.
The volume average sedimentation velocity is evaluated on the basis of a cellular model.
The characteristic dimensions of the circulation zone are obtained on the basis of a numerical solution of Navier-Stokes equations.
Furthermore, these calculations are used for modelling the fast sedimentation of fine particles during their cosedimentation in bidisperse suspension.
It was found that the acceleration of sedimentation of fine particles is determined by the concentration of coarse particles in bidisperse suspension, and the sedimentation velocity of fine fraction is proportional to the square of the coarse and fine particle diameter ratio.
The limitations of the proposed model are ascertained.
