1. A process for making an emulsion, comprising: flowing a first liquid in a process microchannel having a wall with an apertured section; and flowing a second liquid through the apertured section into the process microchannel in contact with the first liquid to form the emulsion, the second liquid being immiscible with the first liquid, the first liquid forming a continuous phase, and the second liquid forming a discontinuous phase dispersed in the first liquid, the process microchannel having a narrowed height or width adjacent to the apertured section, the first liquid flowing through a region upstream of the apertured section having a height or width greater than the narrowed height or width adjacent to the apertured section, the emulsion flowing through a region downstream of the apertured section having a height or width greater than the narrowed height or width adjacent to the apertured section.
