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…
Accurate solution method for the Maxey-Riley equation, and the effects of Basset history
S. Ganga Prasath, Vishal Vasan, Rama Govindarajan
The Maxey-Riley equation has been extensively used by the fluid dynamics community to study the dynamics of small inertial particles in fluid flow. However, most often, the Basset…
Spatio-temporal Patterns of Indian Monsoon Rainfall
Adway Mitra, Amit Apte, Rama Govindarajan +2
The primary objective of this paper is to analyze a set of canonical spatial patterns that approximate the daily rainfall across the Indian region, as identified in the companion p…
A Discrete View of the Indian Monsoon to Identify Spatial Patterns of Rainfall
Adway Mitra, Amit Apte, Rama Govindarajan +2
We propose a representation of the Indian summer monsoon rainfall in terms of a probabilistic model based on a Markov Random Field, consisting of discrete state variables represent…
