Hydrodynamic Origin of Friction Between Suspended Rough Particles
Jake Minten, Bhargav Rallabandi
Tangential interactions between particles play a central role in suspension rheology. We show theoretically that these interactions, often attributed to contact friction, are a dir…
Enhancement and Suppression of Active Particle Movement Due to Membrane Deformations
Adam Hitin Bialus, Bhargav Rallabandi, Naomi Oppenheimer
Microswimmers and active colloids often move in confined systems, including those involving interfaces. Such interfaces, especially at the microscale, may deform in response to the…
Inertio-viscous interactions between particles in oscillatory flow
Xiaokang Zhang, Bhargav Rallabandi
We study the interaction between a pair of particles suspended in a uniform oscillatory flow. The time-averaged behavior of particles under these conditions, driven by inertial and…
Wind-driven collisions between floes explain the observed dispersion of Arctic sea ice
Bryan Shaddy, P. Alex Greaney, Bhargav Rallabandi
The transport of sea ice over the polar oceans plays an important role in climate. This transport is driven predominantly by turbulent winds, leading to stochastic motion of ice fl…
