Significance The simultaneous flow of multiple fluid phases through a porous solid occurs in many natural and industrial processes. Microscale physical mechanisms such as the relative affinity for fluids (i.e., wettability), capillarity, viscosity combine with pore geometry to produce wide variety macroscopic patterns. Pore-scale modeling is an essential tool connect microscale patterns, but quantitative comparisons between different models, experimental data, are lacking. Here, we perform...
Abstract Relative permeability is a critical parameter characterizing multiphase flow in porous media and it strongly dependent on the wettability. In many situations, are nonuniformly wet. To investigate effect of wettability heterogeneity relative two‐phase media, multi‐relaxation‐time color‐gradient lattice Boltzmann model adopted to simulate oil/water with different oil‐wet solid fractions. For water phase, when saturation high, increases increase fraction under constant saturation....
Abstract To investigate the gas flow characteristics in tight porous media, a microscale lattice Boltzmann (LB) model with regularization procedure is firstly adopted to simulate three-dimensional (3D) digital rocks. A shale rock and sandstone are reconstructed study effects of pressure, temperature pore size on flow. The simulation results show that because effect apparent permeability always higher than intrinsic decrease pressure or size, increase temperature, difference between...
A mesoscopic lattice Boltzmann model is implemented for modelling isothermal two-component evaporation in porous media. The based on the pseudopotential multiphase with two components to mimic phase-change component (e.g. water and its vapour) non-condensible dry air), cascaded collision operator used enhance numerical performance. first analysed Chapman–Enskog expansion then validated by theoretical solution of an diffusive problem. We discuss detail implementation wettability a geometric...
The lattice Boltzmann method and pore network model are two types of the most popular pore-scale fluid flow simulation methods. As a direct numerical method, simulates directly in realistic porous structures, characterized by high computational accuracy but low efficiency. On contrary, simplified regular networks real media, which is more computationally efficient, fails to capture detailed structures processes. In past few years, significant efforts have been devoted couple simulate aiming...
Digital core simulation technology, as an emerging numerical method, has gradually come to play a significant role in the study of petrophysical properties. By using this influence micro factors on seepage properties reservoir rock is taken into consideration, making up shortcomings traditional physical experiment. Three-dimensional images are reconstructed by computed tomography scanning technique. Different sizes sub-region were simulated three methods including direct computation...
In this work, a numerical model for isothermal liquid-vapor phase change (evaporation) of the two-component air-water system is proposed based on pseudopotential lattice Boltzmann method. Through Chapman-Enskog multiscale analysis, we show that can correctly recover macroscopic governing equations multicomponent multiphase with built-in binary diffusion mechanism. The verified Stefan problem where measured diffusivity consistent theoretical analysis. then applied to convective drying...
A two-dimensional (2-D) double-distribution lattice Boltzmann method (LBM) is implemented to study isothermal drying of a colloidal suspension considering local nanoparticle effects. The two LBMs solve two-phase flow and transport, respectively. three effects on the fluid dynamics considered in this paper are viscosity increase, surface tension drop rate reduction. proposed model first validated by 2-D suspended droplet for different Péclet numbers, where evolution diameter squared agrees...
A microscale multi-relaxation-time lattice Boltzmann model with the regularization procedure is adopted to simulate gas flow in different porous media. The diffuse reflection boundary condition used deal random solid boundaries. Because of complex geometry pores, characteristic length no longer a constant but function pore locations for rational method proposed obtain local lengths media simulations. simulation results show that characteristics regions are notably different. In continuum...
