Mechanism of droplet motion in the typical micro-channel of porous media

The investigation of a two-phase flow in porous media has significant implications for wide range applications. Previous research focused on exploring the variations and phase fields using experimental numerical methods. However, complex structure introduces many uncertainties that can impact outcomes. In recent years, some scholars have tried to study dynamic mechanics through typical structures eliminate these confounding factors. Therefore, this paper focuses examining patterns dispersed phases with different sizes during displacement process based micro-channel media. Furthermore, examines various dimensionless parameters alterations streamlines as well carrying capacity phases. findings suggest capillary number governs ability continuous transport droplet. Consequently, droplets tend become trapped weak regions. mechanisms dispersive droplet trapping are systematically analyzed by combining simulation results evidence from previous studies. Based findings, puts forth mechanistic suggestions could contribute more effective
