- Enhancement of mixing efficiency in droplets is of great importance to extend the industrial applications of the liquid-liquid twophase flow in micro-scale. In this paper, mixing efficiency in droplets is investigated via the VOF (volume of fluid) method coupledwith UDS (user defined scalar) model. The cross-shaped T junction with a square cross-section is designed and used for dropletformation. Different droplet length and droplet formation frequency are obtained by changing the droplet superficial velocity.Relative velocity fields in different droplet superficial velocity are plotted. Effect of droplet superficial velocity on mixing efficiencyin droplets are quantitatively analyzed based on the scalar distribution uniformity in droplets. Results show that the mixingefficiency varies with the different droplet superficial velocity. A higher droplet superficial velocity makes a higher mixing efficiencydue to the faster inner circulation and shorter droplet length.
