An inertial slender-body theory

Anmol Joshi, Anubhab Roy, Arjun Sharma +1

We present a fully inertial slender-body theory (SBT) that incorporates the effect of fluid inertia on the scale of the length (the "outer" region) as well as the characteristic di…

The merger of co-rotating vortices in dusty flows

Shuai Shuai, Anubhab Roy, M. Houssem Kasbaoui

We investigate the effect of particle inertia on the merger of co-rotating dusty vortex pairs at semi-dilute concentrations. In a particle-free flow, the merger is triggered once t…

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…

Surface and internal gravity waves on a viscous liquid layer: initial-value problems

Ramana Patibandla, Saswata Basak, Anubhab Roy +1

We study a class of initial value problems (IVPs) involving perturbations on a density stratified, quiescent, viscous liquid layer with a free-surface. The geometry is a two-dimens…

Orientation of Finite Reynolds Number Anisotropic Particles Settling in Turbulence

Anubhab Roy, Stefan Kramel, Udayshankar Menon +2

We present experimental and computational results for the orientation distributions of slender fibers and ramified particles settling in an isotropic turbulent flow. The rotational…

Instability of a dusty vortex

Shuai Shuai, Darish Jeswin Dhas, Anubhab Roy +1

We investigate the effect of inertial particles dispersed in a circular patch of finite radius on the stability of a two-dimensional Rankine vortex in semi-dilute dusty flows. Unli…

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…

Linear stability of a rotating liquid column revisited

Pulkit Dubey, Anubhab Roy, Ganesh Subramanian

We revisit the somewhat classical problem of the linear stability of a rigidly rotating liquid column in this communication. Although literature pertaining to this problem dates ba…

Inertio-elastic instability of a vortex column

Anubhab Roy, Piyush Garg, Jhumpal Shashikiran Reddy +1

We analyze the instability of a vortex column in a dilute polymer solution at large and with , the elasticity num…
