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…
