The effect of Reynolds number on the dynamics and wakes of freely rising and falling spheres

M Horowitz, CHK Williamson - Journal of Fluid Mechanics, 2010 - cambridge.org
In this paper, we study the effect of the Reynolds number (Re) on the dynamics and vortex
formation modes of spheres rising or falling freely through a fluid (where Re= 100–15000) …
