Viscoelastic flow of an Oldroyd-B fluid through a slowly varying contraction-expansion channel: pressure drop and elastic stress relaxation
Yali Kedem, Bimalendu Mahapatra, Evgeniy Boyko
Viscoelastic fluid flows in narrow non-uniform geometries are ubiquitous in various engineering applications and physiological flow systems. For such flows, one of the key interest…
Diffusioosmotic flow in a soft microfluidic configuration induces fluid-structure instability
Nataly Maroundik, Dotan Ilssar, Evgeniy Boyko
Diffusioosmotic flow arises in microfluidic configurations due to solute concentration gradients. In soft microfluidic channels, internal pressure gradients generated by diffusioos…
Transient rod-climbing in an Oldroyd-B fluid
Tachin Ruangkriengsin, Rodolfo Brandão, Katie Wu +3
The Weissenberg effect, or rod-climbing phenomenon, occurs in non-Newtonian fluids where the fluid interface ascends along a rotating rod. Despite its prominence, theoretical insig…
Viscoelastic fluid flow in a slowly varying planar contraction: the role of finite extensibility on the pressure drop
Bimalendu Mahapatra, Tachin Ruangkriengsin, Howard A. Stone +1
We analyze the steady viscoelastic fluid flow in slowly varying contracting channels of arbitrary shape and present a theory based on the lubrication approximation for calculating…
