Emergence of Purely Elasto-Plastic Turbulence in Shear Flows
Muhammad Abdullah, Shravan Pradeep, Doug J. Jerolmack +2
We observe the emergence of a distinct, elasticity-driven flow state in a yield-stress fluid in the absence of inertia. Numerical simulations show that this elasto-plastic turbulen…
Geomimicry: Emergent Dynamics in Earth-Mediated Complex Materials
Shravan Pradeep, Emanuela Del Gado, Douglas J. Jerolmack +1
Soils and sediments are soft, amorphous materials with complex microstructures and mechanical properties, that are also building blocks for industrial materials such as concrete. T…
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,…
