Abstract

Surfactants are amphiphilic molecules that adsorb on fluid interfaces, where they reduce the surface tension. If the interface is moving, surface convection can distribute surfactant non-uniformly, creating surface tension gradients or Marangoni stresses. These two phenomena are the keys to understanding the stress response of surfactant-laden interfaces in multiphase flows.
