Nonlocal flow sampling enables vortex trapping of heavy particles
Sachin Kulkarni, Sumithra R. Yerasi, Vishwanath Kadaba Puttanna +3
Most analyses of inertial particle motion in vortical flows rely on the point-particle approximation, in which the fluid velocity is assumed to be linear at the scale of the partic…

Electrostatic force between two charged spherical conductors in an electric field: Matched asymptotic expansion approach
Natarajan Thiruvenkadam, Vishwanath Kadaba Puttanna
In this study, we derive the asymptotic expressions for the electrostatic force between two charged spherical conductors in an electric field. Davis \cite{davis1964two} initially p…
