Capillary rise in porous media
Physica A: Statistical Mechanics and its Applications, 2001Capillary rise experiments were performed in columns filled with glass beads and Berea sandstones, using visual methods to register the advance of the water front. For the glass bead filled columns, early time data are well fitted by the Washburn equation. However, in the experiments, the advancing front exceeded the predicted equilibrium height.

Annual Review of Fluid Mechanics, 1970
The problems of flow and transport in porous media present many fascinating challenges to students of mechanics: and it is surprising that, over the years, these questions have received relatively little attention at the Congresses and Symposia of IUTAM and of its predecessors.

Nature, 1961
THE tortuosity, T, of a porous medium such as sandstone is a quantity that has been interpreted in various and sometimes conflicting ways, particularly its relation to porosity, ϕ, and formation factor, F (refs. 1–4). Tortuosity originally was understood to mean the square of the quotient average length of a flow-line divided by the net distance ...

The method of Nuclear Magnetic Resonance cryoporometry has gained popularity since its inception in 1993 as a non-destructive technique for measuring pore size distributions in the nano-scale range. NMR cryoporometry is a secondary method of measuring pore sizes by observation of the depressed melting point of a confined liquid.

This chapter reviews a series of developments that point in the direction of applying porous media concepts to the description, simulation and optimization of compact systems with complex flow structures, see Bejan et al. [6]. Compact and miniaturized heat exchangers are primary examples of this trend.

This paper briefly surveys the major properties of fractals, their measurements and their application to geological porous media. Our contributions about flow in fractal media are summarized. We indicate some of the ways these works can be extended.

The study of groundwater and porous media flow has become important during the last years in fields as different as civil engineering, aquifer managing and petroleum engineering. The fundamental equations describing these physical phenomena are well known [5], [6] and before the computers allowed them to be solved numerically, many authors developed ...
