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…
The geometry of planar linear flows
Sabarish V Narayanan, Ganesh Subramanian
We identify incompressible planar linear flows that are generalizations of the well known one-parameter family characterized by the ratio of in-plane extension to (out-of-plane) vo…
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…
Two-fluid kinetic theory for dilute polymer solutions
Shiwani Singh, Ganesh Subramanian, Santosh Ansumali
We provide a Boltzmann-type kinetic description for dilute polymer solutions based on two-fluid theory. This Boltzmann-type description uses a quasi-equilibrium based relaxation me…
