“…The interfaces between fluid and deformable structures, free surfaces, and shock waves are considered examples of free boundaries [9][10][11]. Many problems arise while performing numerical simulations of free boundaries [12][13][14] which includes the evolution in time, discrete representation, and techniques and methods that have been used for resolving issues associated with free boundaries in the form of numerical simulations such as finite-difference or finite-element grids [15][16][17][18].…”

The study encompasses the visualization and analysis of dynamic water behavior, pressure drop, and saturation interaction under various boundary condition cases. 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.
