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…
Sedimentation Dynamics of Bodies with Two Planes of Symmetry
Harshit Joshi, Rama Govindarajan
We show that bodies with two planes of symmetry can display a range of behaviors even without inertia. Any such body supports a conserved quantity in its dynamics, and is either a…
