Design of model Boger fluids with systematically controlled viscoelastic properties
Jonghyun Hwang, Howard A. Stone
The subject of viscoelastic flow phenomena is crucial to many areas of engineering and the physical sciences. Although much of our understanding of viscoelastic flow features stems…
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…
