ROTATIONAL SEDIMENTATION IN NEUTRALLY BUOYANT PARTICLE SUSPENSIONS

Rotational sedimentation of neutrally buoyant particles in suspensions in the case of two-dimensional circular flows between two cylinders is studied by mathematical simulation. Particle separation in the absence of gravity is caused by rotation of the inner cylinder. It is revealed that sedimentation depends on particle rotation. Within the framework of the Cosserat continuum, the suspension is considered as a micropolar fluid. The effect of the eccentricity of noncoaxial cylinders on the sedimentation front is investigated.
