Lagrangian dynamics unveil polymer conformation in viscoelastic flows
Louison Thorens, Gabriel Juarez, Jeffrey S. Guasto +1
The complex flow behavior of viscoelastic fluids emerges from a feedback between fluid stress and the out-of-equilibrium conformational dynamics of their constituent polymer chains…
Lagrangian evaluation of polymeric stress in viscoelastic fluids
Mohammad Majidi, Rishu Gandhi, Louison Thorens +3
Polymeric stresses in viscoelastic flows arise from the deformation of polymer chains and are commonly computed using Eulerian constitutive models, in which the conformation tensor…
Stress and stretching regulate dispersion in viscoelastic porous media flows
Manish Kumar, Derek M. Walkama, Arezoo M. Ardekani +1
In this work, we study the role of viscoelastic instability in the mechanical dispersion of fluid flow through porous media at high Peclet numbers. Using microfluidic experiments a…
Lagrangian stretching reveals stress topology in viscoelastic flows
Manish Kumar, Jeffrey S. Guasto, Arezoo M. Ardekani
Viscoelastic flows are pervasive in a host of natural and industrial processes, where the emergence of nonlinear and time-dependent dynamics regulate flow resistance, energy consum…
Self-transport of swimming bacteria is impaired by porous microstructure
Amin Dehkharghani, Nicolas Waisbord, Jeffrey S. Guasto
Motility is a fundamental survival strategy of bacteria to navigate porous environments. Swimming cells thrive in quiescent wetlands and sediments at the bottom of the marine water…
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…
