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…
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…
Data-driven particle dynamics: Structure-preserving coarse-graining for emergent behavior in non-equilibrium systems
Quercus Hernandez, Max Win, Thomas C. O'Connor +2
Multiscale systems are ubiquitous in science and technology, but are notoriously challenging to simulate as short spatiotemporal scales must be appropriately linked to emergent bul…
An Alternative Scaling for Roughness Transitions in Turbulent Flows: The Role of the Internal Boundary Layer
Justin P. Cooke, George I. Park, Douglas J. Jerolmack +1
When turbulent boundary layer flows encounter abrupt roughness changes, an Internal Boundary Layer (IBL) forms. Equilibrium theory breaks down in the nonequilibrium IBL, which may…
