Effect of flow rates of the continuous phase on droplet size in dripping and jetting regimes in a simple fluidic device for coaxial flow

- We investigated the effect of a continuous flow rate on droplet formation.
- The high flow rate resulted in a transition from a dripping to a jetting regime.
- The numerical analysis revealed the effect of the flow rate and the viscosity.
- The critical Capillary number was 0.0136 in the fluidic device system.
