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…
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…
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…
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…
