Shear-induced self-diffusivity in dilute suspensions with repulsive interactions
Anu V S Nath, Pijush Patra, Anubhab Roy
In a dilute non-Brownian suspension undergoing simple shear, pairwise hydrodynamic interactions are fore-aft symmetric at zero Reynolds number and produce no net cross-streamline d…
Trapping and Transport of Inertial Particles in a Taylor-Green Vortex: Effects of Added Mass and History Force
Prabhash Kumar, Anu V. S. Nath, Mahesh Panchagnula +1
We investigate the dynamics of small inertial particles in a two-dimensional, steady Taylor-Green vortex flow. A classic study by Taylor (2022) showed that heavy inertial point par…
Instability of a dusty shear flow
Anu V. S. Nath, Anubhab Roy, M. Houssem Kasbaoui
We study the instability of a dusty simple shear flow where the dust particles are distributed non-uniformly. A simple shear flow is modally stable to infinitesimal perturbations.…
Clustering and chaotic motion of heavy inertial particles in an isolated non-axisymmetric vortex
Anu V. S. Nath, Anubhab Roy
We investigate the dynamics of heavy inertial particles in a flow field due to an isolated, non-axisymmetric vortex. For our study, we consider a canonical elliptical vortex - the…
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…
Transport of condensing droplets in Taylor-Green vortex flow in the presence of thermal noise
Anu V. S. Nath, Anubhab Roy, Rama Govindarajan +1
We study the role of phase change and thermal noise in particle transport in turbulent flows. We employ a toy model to extract the main physics: condensing droplets are modelled as…
