Explicit Runge-Kutta algorithm to solve non-local equations with memory effects: case of the Maxey-Riley-Gatignol equation
Divya Jaganathan, Rama Govindarajan, Vishal Vasan
A standard approach to solve ordinary differential equations, when they describe dynamical systems, is to adopt a Runge-Kutta or related scheme. Such schemes, however, are not appl…
Irregular dependence on Stokes number and non-ergodic transport of heavy inertial particles in steady laminar flows
Anu V. S. Nath, Anubhab Roy, S. Ravichandran +1
Small heavy particles in a fluid flow respond to the flow on a time-scale proportional to their inertia, or Stokes number St. Their behaviour is thought to be gradually modified as…
Geometric characterization of vortex lines in turbulence
Saumav Kapoor, Rama Govindarajan, Siddhartha Mukherjee
Vorticity in turbulent flows is often organized into complex geometries that influence the dynamics. We use a relatively novel approach to describe these geometries: that of obtain…
Effects of equatorially-confined shear flow on MRG and Rossby waves
Mukesh Singh Raghav, Sharath Jose, Amit Apte +1
Linear modal stability analysis of a mean zonal shear flow is carried out in the framework of rotating shallow water equations (RSWE), both under the -plane approximation and in…
The waltz of tiny droplets and the flow they live in
S. Ravichandran, Rama Govindarajan
This article describes the dynamics of small inertial particles centrifuging out of a single vortex. It shows the importance of caustics formation in the vicinity of a single vorte…
Spirographic motion in a vortex
Sumithra Reddy Yerasi, Rama Govindarajan, Dario Vincenzi
Studies of particle motion in vortical flows have mainly focused on point-like particles, either inertial or self-propelled. This approximation assumes that the velocity field that…
