The periodic motion of a disk freely falling in a tube

Résumé

This study is devoted to the rectilinear and periodic paths of an axisymmetric solid body (short-length cylinder and disk of diameter d, thickness h and aspect ratio X= d/h varying between 3 and 10) falling in a vertical tube of diameter D. We investigated the influence of the confinement ratio (S = d/D) on the characteristics of the body motion, for different aspect ratios X and Reynolds numbers (80 < Re < 320), and a density ratio between the fluid and the body close to unity.
