Interfacial viscosity-induced suppression of lateral migration of a surfactant laden droplet in a nonisothermal Poiseuille flow

We examine the role of interfacial viscosity on motion a surfactant-laden droplet across streamlines flow when subjected to thermal gradients. Our results show that both shear and dilatational components necessarily slow down cross-streamline migration droplet, but influence is significantly more imperative. These suggest new strategies manipulation in direction transverse by utilizing variation surface tension interface.
