Comparison between two-dimensional porosity εa and three-dimensional porosity εv was made by a computer simulation study. In the formation of beds based on a random packing model, circles and spheres of equal size were used for the two- and three-dimen-sional systems, respectively. The porosity parameter P was introduced to decide whether the circles or spheres cohere or not when they came into contact with each other. εa and εv for the same P values were then compared. Porosities from the two-and threedimensional regular packing model were also examined. Results obtained by the random packing model were in good agreement with those by the regular packing model, as well as the two-dimensional"open-beam"packing model.
