Perspectives on viscoelastic flow instabilities and elastic turbulence
Sujit S. Datta, Arezoo M. Ardekani, Paulo E. Arratia +20
Viscoelastic fluids are a common subclass of rheologically complex materials that are encountered in diverse fields from biology to polymer processing. Often the flows of viscoelas…
Turbulent duct flow with polymers
Armin Shahmardi, Sagar Zade, Mehdi N. Ardekani +4
We have performed direct numerical simulation of the turbulent flow of a polymer solution in a square duct, with the FENE-P model used to simulate the presence of polymers. First,…
Secondary flows of viscoelastic fluids in serpentine microchannels
Lucie Ducloue, Laura Casanellas, Simon J. Haward +5
Secondary flows are ubiquitous in channel flows, where small velocity components perpendicular to the main velocity appear due to the complexity of the channel geometry and/or that…
Bundling of elastic filaments induced by hydrodynamic interactions
Yi Man, William Page, Robert J. Poole +1
Peritrichous bacteria swim in viscous fluids by rotating multiple helical flagellar filaments. As the bacterium swims forward, all its flagella rotate in synchrony behind the cell…
