This- siniilarity between the structure and velocity distribution of the granular fluid and the usual hard disk fluid suggests that the kinetic theory of Jenkins [9] is applicable.

Based on the obtained results a simple equation is presented for the equivalent permeability of a randomly cracked porous material as a function of the matrix permeability and the
