Polymers in Swarming Bacterial Turbulence
Ranjiangshang Ran, David A. Gagnon, Alexander Morozov +1
We experimentally investigate the effects of polymer additives on the collective dynamics of swarming Serratia marcescens in quasi two-dimensional (2D) liquid films. We find that e…
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.…
