Sedimentation dynamics of passive particles in dilute bacterial suspensions: emergence of bioconvection
Bryan O. Torres Maldonado, Shravan Pradeep, Ranjiangshang Ran +2
Microorganisms are ubiquitous in nature and technology. They inhabit diverse environments ranging from small river tributaries and lakes to oceans, as well as wastewater treatment…
Enhancing Transport Barriers with Swimming Microorganisms in Chaotic Flows
Ranjiangshang Ran, Paulo E. Arratia
We investigate the effects of bacterial activity on the mixing and transport properties of a passive scalar in time-periodic flows in experiments and in a simple model. We focus on…
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…
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.…
