Chaotic dynamics of falling disks
WebDec 7, 1998 · ABSTRACT When a stiff rectangular card is dropped in still air with its long axis horizontal, it often settles into a regular mode of motion; while revolving around its long axis it descends along a path that is inclined to the vertical at a nearly constant angle. WebOct 14, 2024 · The motion of a freely falling thin aluminium plate in water is studied using two-dimensional numerical simulations. The fluid-solid interface is treated using the diffuse interface immersed boundary method. Periodic side-to-side fluttering motion at the small dimensionless moment of inertia $$(I^{*})$$ ( I ∗ ) becomes chaotic in the intermediate …

WebJun 2, 2010 · For a ‘freely falling’ disk of χ = 4, oscillatory motion was observed in a plane with a 21° phase lag between the lateral and angular velocity. The Strouhal number ( Stb) was equal to 0.171, which differs from the St observed in the wake of the fixed disk.
