Abstract
The equations are formulated for the transfer of particles of bidisperse suspension in a disk centrifuge with regard for the interaction of particles with each other and with ambient liquid. The effect of initial concentration of particles on their sedimentation velocity and the sediment layer formation are studied. A possibility is shown for the formation of an internal wave of concentration of small particles as the result of the entrainment of small particles by large particles. The applicability of the formula for numerical differentiation is shown, which describes the temporal variation of particles concentration to determine sedimentation velocity.
