Lagrangian intermittency and vertical confinement in stably stratified turbulence
Arun Kumar Varanasi
We investigate the Lagrangian properties of homogeneous, stratified turbulence at different Brunt-Väisälä frequencies.We show increasing vertical confinement of trajectories with i…

Motion of a sphere in a viscous density stratified fluid
Arun Kumar Varanasi, Ganesh Subramanian
We examine the translation of a sphere in a stably stratified ambient in the limit of small Reynolds () and viscous Richardson numbers (); here, $Re = \frac{ρ…

The rotation of a sedimenting anisotropic particle in a linearly stratified ambient
Arun Kumar Varanasi, Navaneeth K. Marath, Ganesh Subramanian
We derive the torque on a spheroid of an arbitrary aspect ratio sedimenting in a linearly stratified ambient. The analysis demarcates regions in parameter space corresponding t…
