Gelation effects on the spreading of non-Newtonian drops impacting a reactive liquid
Julie Godefroid, David Bouttes, Anselmo Pereira +1
We report in this experimental and numerical study effects of gelation on the early-time spreading ( 10ms) of millimetric non-Newtonian drops of biopolymer and particle suspensi…

Dam break of viscoplastic elliptical objects
Kindness Isukwem, Anselmo Pereira
In this note, we numerically and theoretically analyze the physical mechanisms controlling the gravity-induced spreading of viscoplastic elliptical metric objects on a sticky solid…
