A upscaled lattice Boltzmann method (LBM) for flow simulations in heterogeneous porous media, at both pore and Darcy scales, is proposed in this paper. In the micro-scale simulations, we model flows using LBM with the modified Guo et al. algorithm where we replace the force model with a simple Shan-Chen force model. The proposed upscaled LBM uses coarser grids to represent the effects of the fine-grid (pore-scale) simulations. For the upscaled LBM, effective properties and reduced-order models…

    Multiscale and Multiphysics Flow Simulations of Using the Boltzmann Equation
  • 2019
In the ordinary application of LBM for computing the absolute permeability, the prevailed confusion interpreted as viscosity-dependent permeability is clarified and the underlying rarefaction mechanism that has been commonly oversighted is revealed.
Lattice Boltzmann modelling of intrinsic permeability
To ensure that the LBM simulation is correctly working at the Navier-Stokes hydrodynamic level, the high-order moments have to be negligible, which is particularly important for gas flows in ultra-tight media.
On the unintentional rarefaction effect in LBM modeling of intrinsic permeability
Lattice Boltzmann method (LBM) has been applied to predict flow properties of porous media including intrinsic permeability, where it is implicitly assumed that the LBM is equivalent to the
A Novel Boundary-Type Meshless Method for Modeling Geofluid Flow in Heterogeneous Geological Media
A novel boundary-type meshless method for modeling geofluid flow in heterogeneous geological media was developed. The numerical solutions of geofluid flow are approximated by a set of particular
Coupled fine-scale modeling of the wettability effects: Deformation and fracturing.
It is found that wettability not only controls the fluid propagation patterns but also affects drag forces exerted on the particles during injection such that larger deformations are induced for particles with lower wettable.
Comparative analysis on pore‐scale permeability prediction on micro‐CT images of rock using numerical and empirical approaches
Empirical relation can over‐estimate permeability by a magnification of 50 or more, particularly for those strong heterogeneous structures reported in this study, Nevertheless, empirical relation is still applicable for artificial rocks.


Multiscale Lattice Boltzmann Method for flow simulations in highly heterogenous porous media
A multiscale LBM that can reduce the computational complexity of existing LBM and transfer the information between different scales is implemented and the results of coarse-grid, reduced-order, simulations agree very well with the averaged results obtained using fine grid.
