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…
Enhancement of bacterial rheotaxis in non-Newtonian fluids
Bryan O. Torres Maldonado, Albane Théry, Ran Tao +3
Bacteria often exhibit upstream swimming, which can cause the contamination of biomedical devices and the infection of organs including the urethra or lungs. This process, called r…
