Simulating the molecular density distribution during multi-phase fluid intrusion in heterogeneous media

A computational recovery of multi-phase intrusion was discussed with the modified multi-relaxation time Lattice Boltzmann method (MRT-LBM). Originally proposed dual-matrix computation is developed to address different phase separation and interface tracking for problem. comprehensive validation performed previously theorized observation mercury-water system. Results show that feasible provide converged output under narrowed density difference down 18%. The wetting non-wetting behaviour resulted from form solid–fluid interaction realized arbitrary boundaries, in which contact variance up 4.14%. linear relations described by Laplace's law Washburn's equation were three-dimensionally recovered determination coefficients 96.34% 94.19%, respectively. third fluid status partial-intrusion captured addition complete-intrusion non-occupation porous boundary, demonstrating advanced function phase-separation problems further increased heterogeneity.
