Additionally, the characteristics of the flow in and out of the two-dimensional (2D) channel and the microinjection of water droplets are investigated. The simulations via the Volume of Fluid (VOF) Method include modeling liquid water dynamics with different wall angles in the 2D channel, considering varying air and water inlet velocities. Key parameters such as water volume fraction and pressure drop are thoroughly analyzed. The simulation results demonstrate substantial agreement with the integral characteristics of the process, including dynamics trend, induction time of droplet breakup (saturation phase), and pressure drop. This comprehensive analysis enhances understanding of water droplet dynamics in microchannels and contributes to the optimization of microfluidic devices for a spectrum of applications, from drug delivery to chemical reactions.
