Abstract
A numerical solution is presented for the motion of a neutrally buoyant circular cylinder in Poiseuille and Couette flows between two plane parallel boundaries. The force and torque on a stationary particle were calculated for a wide range of particle sizes and positions across the channel. The resistance matrix, previously calculated, was used to find the translational and angular velocity for a drag and torque free particle. The results are compared with analytical perturbation solutions for a small cylindrical particle situated on the channel centerline, and for the motion of a spherical particle in a circular tube or between plane parallel boundaries. It was found that the behaviour of flow around a cylindrical particle in a channel is qualitatively similar to the behaviour of flow around a spherical particle in a tube, while the flow around a spherical particle in a channel frequently exhibits different trends from the above two cases.
