Chaotic dynamics of falling disks
WebMar 23, 2024 · We investigate experimentally the free-fall motion of a pair of identical disks rigidly connected to each other. The three-dimensional coordinates of the pair of falling disks were constructed to quantitatively describe its trajectory, and the flow structure formed by the disk pair was identified by using dye visualization. The rigidly linked disk pair … WebThe dynamics of spheres rising or falling freely in a quiescent fluid over a wide range of Reynolds number (100 ≤ Re ≤ 15000) were investigated experimentally by Horowitz and Williamson (2010). And two new vertical regimes in which spheres move along a straight vertical path were identified within the range 100 ≤ Re ≤ 210 and 1550 ≤ ...

WebMar 25, 2024 · This paper experimentally investigates the falling regimes of the eccentric disks in water with Reynolds number between 4000 and 21 000 and classifies the descent modes into three types, i.e., the fluttering, chaotic, and tumbling motions, the transition motion, and the new stable descending motion.
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.
