Enhancement of bacterial rheotaxis in non-Newtonian fluids
Bryan O. Torres Maldonado, Albane Théry, Ran Tao +3
Bacteria often exhibit upstream swimming, which can cause the contamination of biomedical devices and the infection of organs including the urethra or lungs. This process, called r…
Mixing in chaotic flows with swimming bacteria
Ranjiangshang Ran, Quentin Brosseau, Brendan C. Blackwell +3
This is a manuscript accepted for publication on Physical Review Fluids, Gallery of Fluid Motion special issue. The manuscript is associated with a poster winner of the 39th Annual…
Flow and aerosol dispersion from wind musical instruments
Quentin Brosseau, Ranjiangshang Ran, Ian Graham +2
In the midst of the COVID-19 pandemic, many live musical activities had to be postponed and even canceled to protect musicians and audience. Orchestral ensembles face a particular…
Phase-separation during sedimentation of dilute bacterial suspensions
Bryan O. Torres Maldonado, Ranjiangshang Ran, K. Lawrence Galloway +3
Numerous natural systems depend on the sedimentation of passive particles in presence of swimming microorganisms. Here, we investigate the dynamics of the sedimentation of spherica…
Bacteria hinder large-scale transport and enhance small-scale mixing in time-periodic flows
Ranjiangshang Ran, Quentin Brosseau, Brendan C. Blackwell +3
Understanding mixing and transport of passive scalars in active fluids is important to many natural (e.g. algal blooms) and industrial (e.g. biofuel, vaccine production) processes.…
Metallic Microswimmers Driven up the Wall by Gravity
Quentin Brosseau, Florencio Balboa Usabiaga, Enkeleida Lushi +5
As a natural and functional behavior, various microorganisms exhibit gravitaxis by orienting and swimming upwards against gravity. Swimming autophoretic nanomotors described herein…
Relating microswimmer synthesis to rheotactic tunability
Quentin Brosseau, Florencio Balboa Usabiaga, Enkeleida Lushi +5
We explore the behavior of micron-scale autophoretic Janus (Au/Pt) rods, having various Au/Pt length ratios, swimming near a wall in an imposed background flow. We find that their…
Fluid rings and droplet arrays via rim streaming
Quentin Brosseau, Petia M. Vlahovska
Tip-streaming generates micron- and submicron- sized droplets when a thin thread pulled from the pointy end of a drop disintegrates. Here, we report streaming from the equator of a…
Electrohydrodynamic Quincke rotation of a prolate ellipsoid
Quentin Brosseau, Gregory Hickey, Petia M. Vlahovska
We experimentally study the occurrence of spontaneous spinning (Quincke rotation) of an ellipsoid in a uniform DC electric field. For an ellipsoid suspended in an unbounded fluid,…
