Abstract
Separation of a liquid + solid suspension in a scroll centrifuge rotor is simulated using a model of slow relative motion of an isolated small-diameter spherical particle in a swirling flow of an incompressible viscous liquid circulating between two rotating coaxial cylinders. The key efficiency parameters of the machine in terms of separation fineness and suspension clarification factor were substantiated, taking account of the kinetic characteristics of the solid phase sedimentation process in the flow in a criterial form. The results of numerical experiment on simulation of spherical powdery substance separation process are presented in dimensional terms and criterial parameters.
