  • In order to capture the relation between permeability and porosity, fluid flowing through two-dimensional random porous media was simulated at pore level by enforcing the no-slip condition on the fluid-solid interface. Fluid flow in two dimensional randomly generated porous media was simulated at the pore-scale using the lattice Boltzmann method (LBM). Random media were constructed by placing solid points with a random distribution. The Darcy's law was verified. The research result shows that the permeability varies exponentially with the porosity at low porosity less than about 0.3, being close agreement with the present result.
