WebConsequently, LB models have been developed for simulating either viscous fingering or dissolution reaction in porous media at the pore scale. On one hand, Liu and Guo 32 32. G. … WebSep 26, 2024 · A pore-scale simulator was developed and used to investigate solvent propagation in porous media based on solvent properties (density, viscosity, and diffusion coefficient). Several models were used to investigate the effect of petrophysical properties, e.g. tortuosity, on the upscaled diffusion coefficient, dispersion tensor, and interfacial …
