TL;DR: In this article, the dynamics of the compound droplet moving in micro-channels were investigated, and it was shown that the deformation or breakup of compound droplets is also different when changing the values of the parameters, including the capillary number, the ratio of the droplet radii, the ratios of the interfacial tension, the size of the secondary channel, the gap size and the cone angle.

TL;DR: In this paper, the authors present the front-tracking-based simulation results of the thermocapillary effects on compound droplets in a certain limited domain, and the effects of these parameters on the compound droplet eccentricity are also considered.

TL;DR: In this paper, the effects of dimensionless parameters on the negative curvature at the trailing surface of a compound droplet moving through a constricted tube were investigated and the most influencing factor was the caillary number.

TL;DR: In this paper, the authors used the front-tracking method to simulate the transition between the two collision modes of multi-core compound droplets in a simple shear flow, and they found that the transition from a reversing to passing-over mode occurs when they increase the value of Ca from 0.01 to 0.63.

TL;DR: In this paper, the solidification process of a compound droplet is numerically simulated by an axisymmetric front-tracking/finite difference technique, and it is found that the outer wetting angle and the growth angle have a strong influence on the solidified droplet.
