Surfactant reorientation under shear: dynamic surface tension and droplet deformation
Alexandra J. Hardy, Abdallah Daddi-Moussa-Ider, Elsen Tjhung
Surfactants are amphiphilic molecules that are generally anisotropic rather than spherical. Their orientation is therefore governed by the interplay between shear-induced reorienta…

Kinetic theory of coupled binary-fluid-surfactant systems
Alexandra J. Hardy, Samuel Cameron, Steven McDonald +2
We derive a self-consistent hydrodynamic theory of coupled binary-fluid-surfactant systems from the underlying microscopic physics using Rayleigh's variational principle. At the mi…
