Contaminated Droplet from Shape Oscillation Damping
The June 26, 2020
When a droplet of one fluid flows through another fluid, its shape oscillates. By filming these vibrations using a fast camera, researchers from the Laboratoire de génie chimique (LGC), including Benjamin Lalanne, professor-researcher Toulouse INP-ENSIACET and the Institut de mécanique des fluides de Toulouse (IMFT) have managed to determine the level of contaminants that the bubble, or drop, carries on its surface.

This work, published in the journal Physical Review Letters, allows a measurement in a medium as fine as the surface of a bubble.
