Introduction
Hydrodynamic focusing is utilizing a focusing stream to confine or reduce a flowing stream. This can be used to help focus a stream or for mixing purposes. Hydrodynamic focusing is passive mixing because it requires no external forces. The focusing stream usually has a higher flowrate which confines the focused stream and pushes it to an area of lower pressure[1].
