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…

DoS Dos and Don'ts
Lucas Warwaruk, Konstantinos Zinelis, Randy H. Ewoldt +2
Dripping-onto-Substrate (DoS) rheometry is a well-established method for measuring the extensional rheology of low-viscosity liquids. However, clear guidelines on the capabilities…
