Shear field has been widely applied to intensify interfacial molecular transport in many chemical engineering processes, and this intensification effect is generally ascribed to the significant increase of contact area between two immiscible phases. Herein, by investigating the molecular transport across water-benzene interfaces subject to shear fields as representative cases, we show that the interfacial molecular transport per unit area of the interface can also be enhanced when surfactants are present. The microscopic mechanism towards the latter shear effect is extensively explored by means of Dissipative Particle Dynamics simulation, and we find that shear flows inhibit the accumulation of surfactants at the interface, and align the remained surfactants along the direction of mass transport, thus favoring the molecular transfer across the interface. This work provides a microscopic insight into the regulation of interfacial transport with shear flow.
