Microfluidic networks

img

Droplets confined between the walls of microfluidic channels behave like point charges of hydraulic resistance. The presence of a droplet in a channel increases the resistance to flow through the channel and decreases the rate of flow through it. This, in turn, influences the trajectories of other droplets traveling through a network. These long-distance interactions together with delays arising from the finite time that a droplet needs to traverse a channel of a given length produce beautifully complex dynamics of flow. We study and strive to understand this dynamics and to find simple vistas for controlling the distribution of droplets in complicated microfluidic networks.
