Understanding the Theory--Experiment Discrepancy in Pressure Drop of Dilute Polymer Solutions in Channel Flows
Nan Hu, Jonghyun Hwang, Evgeniy Boyko +1
The paper investigates why measured pressure drops for dilute polymer solutions in channel flows differ from theoretical predictions, showing that using the correct relaxation time…
Reciprocal theorem for calculating the flow rate of oscillatory channel flows
Shrihari D. Pande, Evgeniy Boyko, Ivan C. Christov
We demonstrate the use of the Lorentz reciprocal theorem in obtaining corrections to the steady flow rate due to flow oscillations in rigid channels. Starting from the unsteady Sto…
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…
