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…

Active Caustics
Rahul Chajwa, Rajarshi, Rama Govindarajan +1
Inertial particles (IPs) in vortical fluid flow cluster strongly, forming singular structures termed caustics for their resemblance to focal surfaces in optics. Here we show that s…

Dynamics and clustering of sedimenting disc lattices
Harshit Joshi, Rahul Chajwa, Sriram Ramaswamy +2
Uniform arrays of particles tend to cluster as they sediment in viscous fluids. Shape anisotropy of the particles enriches these dynamics by modifying the mode-structure and the re…
