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…
