โฆ Synopsis
This paper describes a study of the permeability of anisotropic, nonuniform porous media. The approach is through a statistical model of the microstructure of the porous media. Using a capillary-type model with a distribution of pore sizes and orientations, we show that the permeability can be described by a second-order symmetric tensor regardless of the preferential orientation of the pores in the microstructure. We also show that an ergodic assumption is not always true-spatial averages cannot generally be interchanged with mathematical expectations.

We present theoretical and experimental evidences that show the frequency-dependent permeability K(O) for a porous medium is a scaling function with only two parameters; i.e. K(w)/K(,= K(w/w~), where K(, is the static permeability, CO, is a characteristic frequency
A radiative conductivity model is developed for porous media with a solid opaque phase and a transparent fluid phase. In a first step, an effective semi transparent medium occupying the volume of the real fluid phase is characterized, assuming the validity of the Beer's laws. For example, rod bundle
