The variation of local voidage relative to a given sphere within a random assembly of packed spheres is of interest, particularly in defining local transport coefficient variations. The variation of local voidage with distance from a reference position and the probability distribution of this voida

Voidage profiles in randomly packed beds of uniformly sized spheres are analysed by dividing the bed into a number of concentric layers of equal thickness, and by expressing the void fraction in a layer in terms of the contributions to the solid volume by spheres with centres lying in appropriate ne
The right-hand ordinate of Fig. 9 should read [0\*67~J.
In random-packed beds of spheres, there is an oscillatory variation of local voidage near the containing walls, which dies away into the bed. An expression is derived for this variation by first considering the periodic variation through a regular close-packed hexagonal array of spheres, and then in
