The efficient generation of uniform core-shell droplets have an important role in industrial fields. In this research, mono-disperse core-shell droplets have been generated using a flexural bolt-clamped Langevin-type transducer and two micropore plates. Core-shell droplets were generated in the air when water and silicone oil were used as the core and shell phases. When the applied pressure of core phase, the applied pressure of shell phase and the vibration velocity in micropore were 200 kPa, 150 kPa and 8.2 mm / s, the average diameter and the coefficient of variation of droplets were 207.7 μm and 1.6 %. This result shows that the developed device is effective for the generating of mono-disperse core-shell droplets.
