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…

Autophoresis of a Janus particle near a planar wall: a lubrication limit

Tachin Ruangkriengsin, Günther Turk, Howard A. Stone

We study the self-diffusiophoresis of a spherical chemically active particle near a planar, impermeable wall, with a focus on the influence of particle orientation on propulsion. W…

Revealing Actual Viscoelastic Relaxation Times in Capillary Breakup

Nan Hu, Jonghyun Hwang, Tachin Ruangkriengsin +1

We use experiments and theory to elucidate the size effect in capillary breakup rheometry, where pre-stretching in the visco-capillary stage causes the apparent relaxation time to…

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…

Low-Dimensional Behavior of a Kuramoto Model with Inertia and Hebbian Learning

Tachin Ruangkriengsin, Mason A. Porter

We study low-dimensional dynamics in a Kuramoto model with inertia and Hebbian learning. In this model, the coupling strength between oscillators depends on the phase differences b…

Who killed Lilly Kane? A case study in applying knowledge graphs to crime fiction

Mariam Alaverdian, William Gilroy, Veronica Kirgios +6

We present a preliminary study of a knowledge graph created from season one of the television show Veronica Mars, which follows the eponymous young private investigator as she atte…
