Abstract:Droplet
microfluidics has received increasing attention over the
past decade. This study proposes an easy method for droplet generation
in microchannels by inserting a glass capillary into a microfluidic
chip at required positions. The influences of the capillary insertion
depth (0, 60, and 120 μm), capillary inner diameter (50, 75,
and 100 μm), and two-phase flow rate ratios (2–12) on
the generated droplet length were investigated. The evolution of the
two-phase interface during droplet formation is observed … Show more
