Electrostatic enhancement of particle collision rates in atmospheric flows
Srikumar Warrier, Anubhab Roy, Pijush Patra
Collisional growth of tiny particles is a fundamental process governing the growth of cloud droplets and the aggregation of ash particles in volcanic plumes, with direct implicatio…
Electric field effects on the collision efficiency of uncharged water droplets in a linear flow
Pijush Patra, Anubhab Roy, J. S. Wettlaufer
We study the dynamics of collisions between a pair of uncharged conducting droplets under the influence of a uniaxial compressional flow and an external electric field. The near-fi…
Gravity-induced collisions of uncharged cloud droplets in an electric field
Pijush Patra, Anubhab Roy
We investigate the collisions of uncharged, conducting droplets settling under gravity in the presence of an external electric field. Previous studies have derived a near-field asy…
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…
