Abstract:Quantitative visualization experiments of hollow cylinders falling through a Newtonian liquid were performed. The Archimedes number was in the range 5 to 105, the length/outer diameter ratio of the cylinders was in the range 2.5–10, and the inner/outer diameter ratio was 0–0.85. The definition of the Archimedes number includes the inner and outer cylinder diameters, and it is shown that cylinders with the same Archimedes number having different diameter ratios behave similarly. Particle‐resolved simulations we… Show more
