Abstract

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.

中性浮力颗粒悬浮液的旋转沉降

通过数学模拟研究了两圆柱间二维循环流动中中性浮力颗粒在悬浮液中的旋转沉降。在没有重力的情况下，颗粒分离是由内筒的旋转引起的。揭示了沉降与颗粒旋转有关。在Cosserat连续体的框架内，悬浮液被认为是一种微极流体。研究了非同轴圆柱偏心对沉降锋的影响。
