PocketCaBER and PocketDoS: Low-cost open-source tools for teaching and learning advanced topics in fluid mechanics
Zhaofeng Peng, Lucas Warwaruk, Thomas Livesay +4
We describe two open-source, 3D-printable, flexure-based tools for the quantitative measurement of extensional properties of viscoelastic fluids. These low-cost, portable, and scal…
Measuring Cyclic Tensile Properties of Fluids with Composite Harmonic Exponential Waveforms (CHEW)
L. A. Kroo, R. A. Nicholson, M. W Boehm +3
Building off recent advances on how to practically use exponential shear in a torsional rheometer to compute transient planar extensional viscosity (Kroo et al. 2025a), we extend t…
A unifying perspective on measuring transient planar extensional viscosity from exponential shear
L. A. Kroo, R. A. Nicholson, M. W Boehm +2
Here we present an experimentally practical and robust method to compute the transient extensional viscosity from exponential shear on a wide variety of viscoelastic complex fluids…
Active Foam: The Adaptive Mechanics of 2D Air-Liquid Foam under Cyclic Inflation
Laurel A. Kroo, Matthew Storm Bull, Manu Prakash
Foam is a canonical example of disordered soft matter where local force balance leads to the competition of many metastable configurations. Here we present an experimental and theo…
A Swimming Rheometer: Self-propulsion of a freely-suspended swimmer enabled by viscoelastic normal stresses
Laurel A. Kroo, Jeremy P. Binagia, Noah Eckman +2
Self-propulsion at low Reynolds number is notoriously restricted, a concept that is commonly known as the "scallop theorem". Here we present a truly self-propelled swimmer (force-…
Excitable mechanics embodied in a walking cilium
Matthew S. Bull, Laurel A. Kroo, Manu Prakash
Rapid transduction of sensory stimulation to action is essential for an animal to survive. To this end, most animals use the sub-second excitable and multistable dynamics of a neur…
