Quantitative measurement of fluid inertial effects in confined Brownian motion
Quentin Ferreira, Pablo Palacios-Alonso, Harshit Joshi +3
The hydrodynamic response of Brownian particles in liquids is fundamentally altered by inertial forces arising from unsteady momentum transport in the surrounding fluid. These forc…
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…
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…
Electrostatic interactions between anisotropic particles
Harshit Joshi, Anubhab Roy
We investigate the electrostatic interactions between two charged anisotropic conductors using a combination of asymptotic and numerical methods. For widely separated particles, we…
