Anomalous dispersion of microswimmer populations
Laxminarsimharao Vennamneni, Piyush Garg, Ganesh Subramanian
We examine the longitudinal dispersion of spheroidal microswimmers in pressure-driven channel flow. When time scales corresponding to swimmer orientation relaxation, and diffusion…
Inertial migration of a sphere in plane Couette flow
Prateek Anand, Ganesh Subramanian
We study the inertial migration of a torque-free neutrally buoyant sphere in wall-bounded plane Couette flow over a wide range of channel Reynolds numbers, , in the limit of…
Understanding viscoelastic flow instabilities: Oldroyd-B and beyond
Hugo A. Castillo Sanchez, Mihailo R. Jovanovic, Satish Kumar +4
The Oldroyd-B model has been used extensively to predict a host of instabilities in shearing flows of viscoelastic fluids, often realized experimentally using polymer solutions. Th…
Perspectives on viscoelastic flow instabilities and elastic turbulence
Sujit S. Datta, Arezoo M. Ardekani, Paulo E. Arratia +20
Viscoelastic fluids are a common subclass of rheologically complex materials that are encountered in diverse fields from biology to polymer processing. Often the flows of viscoelas…
A continuous pathway between the elasto-inertial and elastic turbulent states in viscoelastic channel flow
Mohammad Khalid, V. Shankar, Ganesh Subramanian
We show that viscoelastic plane Poiseuille flow becomes linearly unstable in the absence of inertia, in the limit of high elasticities, for ultra-dilute polymer solutions. While in…
The center-mode instability of viscoelastic plane Poiseuille flow
Mohammad Khalid, Indresh Chaudhary, Piyush Garg +2
A modal stability analysis shows that plane Poiseuille flow of an Oldroyd-B fluid becomes unstable to a `center mode' with phase speed close to the maximum base-flow velocity, $U_{…
