Pore size in model particle gels

The porosity of model particle gel networks with a range of textures is investigated using some established methods. The pore-size distribution function distinguishes clearly between simulated gels of differing texture. The chord length distribution appears less useful, although clearly it does become bi-modal for coarse configurations, corresponding to the appearance of distinct high and low density regions. A box-counting analysis is presented for describing the fractal scaling properties of the voids.
