The flow field due to a sphere moving in a viscous, density stratified fluid
Ramana Patibandla, Anubhab Roy, Ganesh Subramanian
We study the flow field induced by a sphere translating in a viscous density-stratified ambient, specifically, in the limit of small Reynolds , and viscous Rich…
Evidence of Chaotic Mixing in the Alveolar Region of the Lung
Prabhash Kumar, Prahallada Jutur, Anubhab Roy +1
We report an experimental and numerical investigation to study the role of asymmetry in the expansion-contraction of the acinar wall on the particle transport in the acinus. We mod…
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…
