Hydrodynamic instabilities in a 2-D sheet of microswimmers embedded in a 3-D fluid
Viktor Škultéty, Dóra Bárdfalvy, Joakim Stenhammar +2
A collection of microswimmers immersed in an incompressible fluid is characterised by strong interactions due to the long-range nature of the hydrodynamic fields generated by indiv…
Interplay between Brownian and hydrodynamic tracer diffusion in suspensions of swimming microorganisms
Henrik Nordanger, Alexander Morozov, Joakim Stenhammar
The general problem of tracer diffusion in non-equilibrium baths is important in a wide range of systems, from the cellular level to geographical lengthscales. In this paper, we re…
Linear stability analysis of purely elastic travelling wave solutions in pressure driven channel flows
Martin Lellep, Moritz Linkmann, Alexander Morozov
Recent studies of pressure-driven flows of dilute polymer solutions in straight channels demonstrated the existence of two-dimensional coherent structures that are disconnected fro…
Active turbulence and spontaneous phase separation in inhomogeneous extensile active gels
Renato Assante, Dom Corbett, Davide Marenduzzo +1
We report numerical results for the hydrodynamics of inhomogeneous lyotropic and extensile active nematic gels. By simulating the coupled Cahn-Hilliard, Navier-Stokes, and Beris-Ed…
Yield-stress transition in suspensions of deformable droplets
Giuseppe Negro, Livio Nicola Carenza, Giuseppe Gonnella +3
Yield-stress materials, which require a sufficiently large forcing to flow, are currently ill-understood theoretically. To gain insight into their yielding transition, here we stud…
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…
