Summary Effects of the size of the box which spherical particles are deposited into on the porosity of a resulting particle aggregate have been simulated and examined, particularly to find out if the extrapolation method often used by experimenters is certainly right; this method is based on the empirical fact that the porosity is inversely proportional to the box size. The simulation justified the inverse proportionality and demonstrated that the porosity obtained by the simulated extrapolation coincides with that by the simulation with use of conventional cyclic boundary conditions. This coincidence implies the extrapolation gives the right experimental results of porosities and also that the conventional cyclic boundary condition method is a really strong method to construct a random packing of “infinite” extent by simulation. An effect of the box wall has also been explored in view of area porosisties and cumulative distribution of diameters of circles appearing on aggregate cross-sections. Furthermore, slopes of the straight line of the porosity versus ratio of the particle diameter to the box size have been discussed in terms of two statistical geometry models.
