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,…
Understanding the rheology of kaolinite clay suspensions using Bayesian inference
Ranjiangshang Ran, Shravan Pradeep, Sébastien Kosgodagan Acharige +4
Mud is a suspension of fine-grained particles (sand, silt, and clay) in water. The interaction of clay minerals in mud gives rise to complex rheological behaviors, such as yield st…
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…
Jamming Distance Dictates Colloidal Shear Thickening
Shravan Pradeep, Mohamad Nabizadeh, Alan R. Jacob +2
We report experimental and computational observations of dynamic contact networks for colloidal suspensions undergoing shear thickening. The dense suspensions are comprised of ster…
