摘要

Rate effect is observed during the pressurized liquid infiltration into mesoporous materials. The infiltration pressure increases with loading rate, which is associated with liquid viscosity. Through parametric experiments on liquid composition and temperature, the mesoscale fluid is shown to retain some characteristics of laminar flow, influenced by the shear liquid viscosity force, as well as the nanoscale solid–liquid interfacial properties. The effective viscosity at the mesoscale increases with its bulk counterpart in a power law, but due to the mesoscale boundary condition, it is much lower than the bulk value, and their gap becomes larger for more viscous liquids.
