“…One approach is based on the continuum equations of flow and mass transport in which the transport coefficients, such as the dispersion coefficients, and other physical parameters are provided as the input, determined a priori by experimental measurements. Typical of such studies are those of Zimmerman and Homsy (1992a, b), Riaz and Meiburg (2004), Riaz et al (2006) and Mohiuddina et al (2013). This approach provides an overall picture of what happens in the porous medium, but it is difficult to incorporate into such models detailed information about the spatial heterogeneities of the pore space.…”

We develop a comprehensive pore-network model for simulation of miscible displacements in laboratory-scale porous media. The goal is to study the effect of porescale heterogeneity, and in particular pore-size distribution and pore connectivity, as well as mobility ratio M on miscible displacements, and compute the effective longitudinal dispersion coefficient as a function of M. At the pore level the phenomenon is described by the convective-diffusion equation with a Taylor-Aris dispersion coefficient. Extensive simulations indicate the strong effect of the connectivity and broadness of the pore-size distribution on the efficiency of the displacement process. Moreover, the model enables us to compute the effective dispersion coefficient as a function of the mobility ratio of the two fluids that, to our knowledge, has not been calculated before. Simple generalization of the model will make it possible to study more complex related phenomena, and in particular injection of CO 2 into a pore space that contains saline water.

“…Existing studies on the miscible viscous fingering in porous media at the pore scale have mostly focused on the influence of factors such as viscosity ratio, porous media structure (Liu and Guo, 2015;Elgahawy and Azaiez, 2021), and chemical reactions (Lei and Luo, 2019;, ignoring the effect of the gravity field. However, the interplay between the viscosity ratio and the gravity determines the interfacial instabilities (Jiao and Hötzl, 2004;Jiao and Maxworthy, 2008;Zeeshan Mohiuddin and Stokes, 2013). The viscosity ratio and the gravity either stabilize or destabilize the interface.…”

Introduction: This study investigates the displacement of two miscible fluids within an inclined porous medium at the pore scale, highlighting how the pore-scale microstructure, inclination angle, and viscosity ratio affect the interfacial instability between two fluids during displacement processes.Methods: The lattice Boltzmann Method (LBM) is employed to solve the governing equations. Two distribution functions are used to simulate the velocity field and the concentration field, respectively.Results and discussion: An increase in inclination angle exacerbates the interfacial instability between fluids and the viscous fingering phenomenon. This viscous fingering expands the sweep range of displacing fluids, which improves the displacement efficiency. When θ > 50°, further increase in inclination angle will not cause significant changes in displacement efficiency. In addition, the viscosity ratio is a key factor affecting displacement efficiency. The larger the viscosity ratio, the greater the displacement efficiency. Furthermore, the critical viscosity ratio has been found, and any increase in the viscosity ratio above the critical value will not affect the displacement efficiency.
