Effects of Surfactant Solubility on the Hydrodynamics of a Viscous Drop in a DC Electric Field

open access: yes, 2020
The physico-chemistry of surfactants (amphiphilic surface active agents) is often used to control the dynamics of viscous drops and bubbles. Surfactant sorption kinetics has been shown to play a critical role in the deformation of drops in extensional ...
