New Insights and Phase Diagram into Achieving Monodispersity in Microfluidic Generated Drops

Monodispersity is an important property of microfluidic drops that is achievable by the precise control of microfluidics. By investigating spacing between two consecutive drops during their generation, a transition between dripping and intermediate dripping regimes is clearly identified. Moreover, we developed a theoretical model which accurately predicts our experimental findings. Finally, a new phase diagram offers interesting research opportunities for controlling the size of monodispersed drops.
