Description

The typical characteristic of a thin porous layer is that its thickness is much smaller than its in-plane dimensions. A stack of thin porous layers creates contact interfaces, whose properties are quite different with thin layers. Determining the hydraulic properties is essential to understand and model fluid flow in thin porous media. The validity of classical methods in thin porous media is doubtful, because of the huge differences between thin porous media and normal porous media.
In this work, we constructed a relatively simple experimental setup for measuring the hydraulic properties for a stack of thin porous layers. We performed a series of experiments using the uniform-gradient-flow method. Both saturation and water pressure values were measured for different thicknesses of layers.
