“…However, the traditional CFD method has some problems, including a large computational volume, low computational accuracy, difficulty in dealing with complex equations, and simple boundary conditions. To solve these problems, scholars [97][98][99] proposed adopting the LBM method to conduct CO2 microscopic flow numerical simulations. Compared with the traditional CFD method, the LBM method can be programmed on a computer system with parallel processing capability.…”

To prevent CO2 leakage and ensure the safety of long-term CO2 storage, it is essential to investigate the flow mechanism of CO2 in complex pore structures at the pore scale. This study focuses on reviewing the experimental, theoretical, and numerical simulation studies on the microscopic flow of CO2 in complex pore structures during the last decade. For example, advanced imaging techniques, such as X-ray computed tomography (CT) and nuclear magnetic resonance (NMR), are used to reconstruct the complex pore structures of rocks. Mathematical methods, such as Darcy's law, Young–Laplace’s law, and the Navier-Stokes equation, are used to describe the microscopic flow of CO2. Numerical methods, such as the lattice Boltzmann method (LBM) and pore network (PN) model, are used for numerical simulation. The application of these experimental and theoretical models and numerical simulation studies is discussed, considering the effect of complex pore structures. Finally, future research is suggested to focus on: (1) Conducting real-time CT scanning experiments of CO2 displacement combined with the developed real-time CT scanning clamping device to realize real-time visualization and provide quantitative description of the flow behavior of CO2 in complex pore structures; (2) The effect of pore structures change on the CO2 flow mechanism caused by the chemical reaction between CO2 and the pore surface, the flow theory of CO2 considering wettability and damage theory in a complex pore structures; (3) The flow mechanism of multi-phase CO2 in complex pore structures; (4) The flow mechanism of CO2 in the pore structures at multiscale and the scale upgrade from microscopic to mesoscopic to macroscopic. Generally, this study focuses on reviewing the research progress of CO2 flow mechanisms in complex pore structures at the pore scale and affords an overview of potential advanced developments to enhance the current understanding of CO2 microscopic flow mechanisms.

“…LBM has been successfully applied to the simulation of fluid flow including single-and multiphase flows [13,14], natural convection caused by temperature gradient [15,16], and double diffusive natural convection in a cavity with a hot square obstacle inside [17], Rayleigh convection generated by a local high concentration gradient in the gas-liquid mass transfer process of CO 2 absorption into liquid ethanol [18,19], density driven natural convection in anisotropic and heterogeneous saline aquifers [4]. Cheng et al [3] have simulated the density driven…”

“…The simulation results, which were confirmed by the PIV experiments, reproduced the meso-scale flow behaviors and mass transfer characteristics. In addition, with the help of Schlieren observation and LBM-FDM, Chen et al [27] revealed the 3D features of interfacial convection in the CO 2 -ethanol system. However, even now, it is still rather inconvenient to experimentally obtain the real-time velocity and concentration fields at the same time.…”
