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