Abstract

Motion of a single macroscopic particle in a liquid flowing through a narrow channel with slightly non-parallel walls is studied by a visualization method. The experiment is limited to the region of slight inertia effects, <i>Ar</i> &lt; 500. Three kinematic characteristics of the particle motion in the channel, <i>viz.</i> settling velocity in a still liquid, as well as longitudinal and lateral migration velocities under non-zero flow, are determined and correlated in dependence on the operation parameters. Both the longitudinal characteristics strongly depend on the particle-to-channel size ratio and are only slightly affected by inertia effects. On the other hand, the inertia effects play an essential role in the mechanism of lateral migration.
