Viscous Settling of Bravais Unit-Cells
Sebastian Bürger, Harshit Joshi, S Ganga Prasath +2
We study experimentally and theoretically the Stokesian settling of a well-known class of porous shapes: Bravais lattice unit-cells, whose porosity we vary controllably by changing…

Basset-Boussinesq history force and inertia are relevant for unsteady particle settling dynamics
Tomek Jaroslawski, Divya Jaganathan, Rama Govindarajan +1
Our experiments on a sphere falling under gravity in Stokes flow show significant history effects. We observe an algebraic, not exponential, relaxation rate to the terminal velocit…

Trapping and extreme clustering of finitely-dense inertial particles near a rotating vortex pair
Saumav Kapoor, Divya Jaganathan, Rama Govindarajan
Small heavy particles cannot get attracted into a region of closed streamlines in a non-accelerating frame (Sapsis & Haller 2010). In a rotating system, however, particles can get…
