Definition

Flow bifurcation in microchannels is discussed in this entry. In this entry, flow bifurcation refers to geometrical bifurcation. Specifically, the transport of droplets in microchannel where a mother branch bifurcates into two daughter branches with thermocapillary effects is examined.

Overview

Microchannel bifurcations have been employed in manipulating droplets. These manipulations include but are not limited to droplet fusion and splitting. Fusing of droplets has been demonstrated using a microchannel with three bifurcating branches [1]. A bifurcating T-junction can be employed to split a droplet into two daughter droplets of smaller size [2]. The relative size of the two daughter droplets is determined by the length of the branches. A longer branch creates larger resistance to flow, therefore creating smaller daughter droplet. In the extreme case where one of the branches is sufficiently long, the droplet does not break but...
