| Abstract: | Gaseous flow regimes through tight porous media are described by rigorous application of a unified Hagen–Poiseuille-type equation.
Proper implementation is accomplished based on the realization of the preferential flow paths in porous media as a bundle
of tortuous capillary tubes. Improved formulations and methodology presented here are shown to provide accurate and meaningful
correlations of data considering the effect of the characteristic parameters of porous media including intrinsic permeability,
porosity, and tortuosity on the apparent gas permeability, rarefaction coefficient, and Klinkenberg gas slippage factor. |
