Abstract In this study, a two-dimensional approach is elaborated to study with
the lattice Boltzmann method (LBM) the seepage of water in the pores of a soil.
Firstly, the D2Q9 model is selected to account for the discrete velocity distribution of water flow. In particular, impermeability is considered as macroscopic
boundary condition for the left and right domain sides, while the upper and lower
boundaries are assumed to behave as pressure boundaries controlled by different
densities. The micro-boundary conditions are implemented through the standard
rebound strategy and a non-equilibrium extrapolation scheme. Matlab is used
for the development of the related algorithm.… More >
