Effect of droplet superficial velocity on mixing efficiency in liquid-liquid droplet flow
(2019) XII International Conference on Computational Heat, Mass and Momentum Transfer, ICCHMT 2019- Abstract
- 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 coupled
with UDS (user defined scalar) model. The cross-shaped T junction with a square cross-section is designed and used for droplet
formation. 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 efficiency
in droplets are quantitatively analyzed based on the scalar distribution...

efficiency varies with the different droplet superficial velocity. A higher droplet superficial velocity makes a higher mixing efficiency
due to the faster inner circulation and shorter droplet length. (Less)
