Pinch-off dynamics for a Newtonian liquid thread draining in a viscoplastic medium
Shu Yang, Konstantinos Zinelis, Sourojeet Chakraborty +1
The pinch-off dynamics of a Newtonian liquid thread embedded in a viscoplastic medium is investigated using direct numerical simulations and theory. Thread breakup occurs below a n…

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…

Viscoelastic Worthington jets & droplets produced by bursting bubbles
Ayush K. Dixit, Alexandros Oratis, Konstantinos Zinelis +2
Bubble bursting and subsequent collapse of the open cavity at free surfaces of contaminated liquids can generate aerosol droplets, facilitating pathogen transport. After film ruptu…
