Effective permeability of a two-dimensional heterogeneous permeability field is calculated by a lattice Boltzmann algorithm. Our algorithm and codes are validated by series and parallel modes. Results for a chessboard mesh show that our method solves the singularity problem naturally among grids with inhomogeneous permeability, with a higher numerical accuracy on coarse grids compared with commercial software. Therefore, this method has more promising applicability and prospects. PB Begell House LK https://www.dl.begellhouse.com/journals/49dcde6d4c0809db,5d0c31fa47da4822,1ef2eca179b3c495.html
