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…

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…

The fluid dynamics of a viscoelastic fluid dripping onto a substrate
Konstantinos Zinelis, Thomas Abadie, Gareth H. McKinley +1
Extensional flows of complex fluids are pivotal in industrial applications like spraying, atomisation, and microfluidic drop deposition. The Dripping-on-Substrate (DoS) technique i…
