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…

A unifying Rayleigh-Plesset-type equation for bubbles in viscoelastic media
Alexandros T. Oratis, Kay Dijs, Guillaume Lajoinie +2
Understanding the ultrasound pressure-driven dynamics of microbubbles confined in viscoelastic materials is relevant for multiple biomedical applications, ranging from contrast-enh…

Coalescence of bubbles in a viscoelastic liquid
Alexandros T. Oratis, Vincent Bertin, Jacco H. Snoeijer
When two bubbles submerged in a liquid are brought closely together, the intermediate liquid film separating the bubbles begins to drain. Once the film ruptures, the bubbles coales…
