Particle trapping in vortex crystals
Jean-Régis Angilella, Jean-Régis Angilella, S. Ravichandran
We study the motion of inertial particles in two-dimensional inviscid and viscous vortex crystals, where vortices are placed at the tips of a regular polygon, and determine the con…

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…

Prograde and meandering wall modes in rotating Rayleigh-Bénard convection with conducting walls
S. Ravichandran, J. S. Wettlaufer
We use direct numerical simulations to study convection in rotating Rayleigh-Bénard convection in horizontally confined geometries of a given aspect ratio, with the walls held at…
