Expansion of a hole in a viscoelastic liquid sheet
Tachin Ruangkriengsin, Rodolfo Brandão, Howard A. Stone
Experiments on highly viscous polymeric films show that punctured holes expand exponentially in time, without sustained accumulation of liquid near the rim. This response departs f…
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…
Approximating pressure-driven Stokes flow using the principle of minimal excess dissipation
Tachin Ruangkriengsin, Marcus Roper
Stokes' equations model microscale fluid flows including the flows of nanoliter-sized fluid samples in lab-on-a-chip systems. Helmholtz's dissipation theorem guarantees that the so…
