Understanding droplet collisions through a model flow: Insights from a Burgers vortex
Lokahith Agasthya, Jason R. Picardo, S. Ravichandran +2
We investigate the role of intense vortical structures, similar to those in a turbulent flow, in enhancing collisions (and coalescences) which lead to the formation of large aggreg…

Flow structures govern particle collisions in turbulence
Jason R. Picardo, Lokahith Agasthya, Rama Govindarajan +1
The role of the spatial structure of a turbulent flow in enhancing particle collision rates in suspensions is an open question. We show and quantify, as a function of particle iner…
