Summary: A physics-informed machine learning model is developed to replace numerical simulations of porous media. The model accurately predicts flow fields by learning the communications among grid cells. Generalization of permeability with high accuracy is challenging due to the random arrangements of particles, and building a comprehensive database for different grain/pore arrangements is expensive. The developed model uses deep learning to represent porous media and combines neural network architectures to avoid gradient issues, with the continuity and momentum conservation equations embedded in the loss function.

Summary: The Lattice Boltzmann method was used to simulate propane-air mixture combustion in porous media with different grain shapes. The effects of these shapes on flow fields, temperature fields, and flame characteristics were investigated. It was found that grains with sharp corners in the porous media provided the highest reverse flow, while rectangular and triangular grains provided the highest and least pressure drop, respectively.

Summary: Studying the fault damage zone of the Jorgillo Fault in northern Chile using X-ray micro-computed tomography and paleopermeability modeling, the research reveals the 3D-spatial distribution of fault damage and related anisotropy in permeability. The permeability anisotropy distribution in the damage zone is related to off-fault damage generation and could be explained by tip propagation fault growth and dynamic rupture due to earthquakes under the fault-valve mechanism.

Summary: The study examined the effects of fracture aperture, strike, and connectivity on the permeability of fractured porous media, revealing that a greater strike factor and smaller tortuosity lead to higher permeability. Moreover, higher connectivity coefficient in the fracture network results in higher permeability for fracture-pore media, with a tendency toward dominant channel effects. Ultimately, connectivity in the fracture network has a greater impact on the seepage ability of fracture-pore media compared to fracture aperture and strike.

Summary: Numerical solutions of the reaction-diffusion system of equations in three dimensions are used to generate porous media structures of chosen porosity. The generated geometries are characterized by their Minkowski functional densities and average pore diameter. The study finds that the permeability and Forchheimer parameter exhibit two distinct behaviors aligned with the two generated types of geometries. Furthermore, the mean curvature is found to be an important parameter alongside porosity for characterizing the permeability.

Summary: The presented method is applicable to a general matrix lattice Boltzmann method for deriving equivalent finite difference equations and subsequent equivalent partial differential equations, which can be used for advection diffusion equations and Navier-Stokes equations. The algorithm for obtaining coefficients and deriving equations is implemented for different velocity models, ensuring finiteness and convergence after a certain number of iterations. The implementation is done in C++ with the GiNaC library and is available under the GNU general public license (GPL).

Summary: In this study, the permeability of porous media with sphere packing is investigated using the lattice Boltzmann method (LBM) and experimental studies. The accuracy of LBM is verified and the effects of porosity and particle size on permeability are studied. A modified Kozeny-Carman equation is proposed and validated through experimental tests.

Summary: The flow through a porous medium is significantly affected by boundary conditions, which are often assumed to be static. Changes in the medium due to swelling and erosion have been considered in extending existing lattice-Boltzmann models. The competition between swelling and erosion determines the steady state, with a transition between regimes where either swelling or erosion dominates.

Summary: The research proposes two 3D models to overcome numerical instability issues in high-Peclet flows, coupling a Lattice-Boltzmann Navier-Stokes solver with an advection-diffusion model or a finite-difference algorithm. Through improving numerical diffusivity and validation tests, it is shown that the coupled finite-difference/Lattice-Boltzmann model provides stable solutions in the case of infinite Pe and Pe(g).

Summary: This study investigates the heat transfer characteristics of natural convection of large Prandtl number fluids in porous media using a novel lattice Boltzmann approach. It reveals significant differences between large and small Prandtl number fluids, with the former more easily transitioning from a convection-dominated process to a conduction-dominated one in porous media.

Summary: This paper investigates the migration and deposition of suspended particles in porous media, analyzing the coupled effects of concentration, flow rate, and pH on the clogging mechanism. The study shows that critical velocity and repulsive barrier play crucial roles in particle deposition, with permeability impairment increasing with concentration and pH affecting the repulsive barrier.

Summary: This paper simulated the seepage characteristics of a soil-rock mixture (SRM) at different sizes using the improved Monte Carlo method and the lattice Boltzmann method. Through 342 simulation experiments, it was found that the permeability of the SRM gradually increased with an increase in resolution (R) and tended to stabilize at R = 60 ppi. The dispersion degree of the model permeability obtained by different segmentation types followed the order of center < random < equal < top at the same model feature size (S), and the permeability gradually decreased with an increase in S and stabilized at S = 80 mm.
