Lattice Boltzmann Simulation of Flow in Random Porous Media Constructed by Quartet Structure Generation Set

Based on the wide application background of flow in porous media, this paper simulates the seepage of porous media. A porous medium model was generated by quartet structure generation set and the micro solid phase in the model was filtered. Then simulates the seepage in a pressure-driven porous medium by lattice Boltzmann method D2Q9 model. By comparing the simulation results with the calculation results of the well-known CK theoretical formula, it is found that the error is small when the porosity is high (the error is about 6% whenφ= 0.9). Results have shown that the permeability of porous media and the flow results of pore size obtained by the method in this paper are more accurate at high porosity.
