Chaotic dripping in an electro-coflow setting

Drops formed in a dripping regime usually present monodispersity in size when generated at low flow rates. At higher flow rates, the periodic character of the process is lost, and it exhibits chaotic behavior, affecting the size of the drop, and the frequency of formation. In this work, we study the generation of emulsion drops in glass-based microfluidic devices. The emulsion drops formed in a coflow setting showed different routes to chaos, period-doubling and intermittencies, depending on the properties of the used fluids. In an electro-coflow setting, we studied how this non-periodic behavior affects the transition from the dripping regime to the microdripping one.
