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…
Origins of complexity in the rheology of Soft Earth suspensions
Shravan Pradeep, Paulo E. Arratia, Douglas J. Jerolmack
When wet soil becomes fully saturated by intense rainfall, or is shaken by an earthquake, it may fluidize catastrophically. Sand-rich slurries are treated as granular suspensions,…
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…
