“…The lattice Boltzmann method (LBM) is a meso-scale CFD approach based on a discretized form of the Boltzmann transport equation that can recover hydrodynamic equations through the Chapman-Enskog expansion [9,10]. Its algorithm allows an easy treatment of complex solid boundaries on a regular Cartesian grid [11,12], and local calculation of macroscopic quantities enables efficient parallel computing [13,14]. These features makes the LBM particularly suitable for fluid flow simulation through fibrous porous materials with highly-complex microstructure.…”

“…They further applied the 3-D numerical model to investigate the changes to rock mechanical properties caused by reactive transport (Liu & Mostaghimi, 2017b). Wang and Zhu (2018) developed a LB reactive transport model coupled to heat transfer and studied the ablation process of carbon fibers. In conclusion, the LB method is a promising tool for gas hydrate reactive transport research involving multicomponent multiphase fluid flow, mass transport, and heat transfer in porous media.…”

Fundamental understanding of pore‐scale methane hydrate dissociation in porous media is important to evaluate submarine slope stability and potential utilization of methane resources. In this paper, a general pore‐scale framework based on the lattice Boltzmann (LB) method is established for reactive transport coupled with nonisothermal multiple physicochemical processes in porous media. The framework combines the gas hydrate dissociation kinetic model, the single‐phase flow LB model, the mass transport LB model, and the conjugate heat transfer LB model. The pore‐scale framework is validated by several benchmark problems and then employed to investigate the endothermic dissociation process of methane hydrate with pore‐filling and grain‐coating habits in porous media. The methane hydrate endothermic dissociation behavior coupled with nonlinear nonisothermal multiple physicochemical processes involving intrinsic dissociation dynamics, gas flow, mass transport, phase change heat transfer, and conjugate heat transfer is well captured by the framework. The phase change of methane hydrate dissociation and pore structure evolution for different pore habits of hydrate are well depicted, and some insights about the dissociation front advancement and temperature distributions are also obtained. In addition, the effects of temperature field, inlet temperature, and inlet pressure on methane hydrate dissociation are investigated. The pore‐scale methane hydrate dissociation helps to advance our understanding of permeability‐saturation variation relation for continuum models.

“…On the other hand, it can be applied to a broad variety of application fields. In the context of porous media these are for example,: oil and gas flow in underground formations (H. Li et al., 2015; Ren et al., 2015), oil recovery with in situ combustion (Lei & Luo, 2022), pore structure evolution in cement manufacturing (Patel et al., 2014, 2021), combustion of porous solid rocket fuel (Wang & Zhu, 2018), water transport and reactions in fuel cells (Sarkezi‐Selsky et al., 2022), multi‐phase flow in batteries (Danner et al., 2016; Lautenschlaeger, Prifling, et al., 2022; Lautenschlaeger, Weinmiller, et al., 2022), and dissolution and precipitation reactions in stone formations (Chen et al., 2014; Kang & Lichtner, 2013; Tian & Wang, 2017; L.

A general and local reactive boundary condition (RBC) for studying first‐order equilibrium reactions using the lattice Boltzmann method is presented. Its main characteristics are accurate reproduction of wall diffusion, invariance to the wall and grid orientation, and absence of nonphysical artifacts. The scheme is successfully tested for different benchmark cases considering diffusion, advection, and reactions of fluids at solid‐liquid interfaces. Unlike other comparable RBCs from the literature, the novel scheme is valid for a large range of Péclet and Damköhler numbers, and shows realistic pattern formation during precipitation. In addition, quantitative results are in good accordance with analytical solutions and values from literature. Combining the new RBC with the rest fraction method, Péclet‐Reynolds ratios of up to 1,000 can be achieved. Overall, the novel RBC accurately models first‐order reactions, is applicable for complex geometries, and allows efficiently simulating dissolution and precipitation phenomena in fluids at the pore scale.
