A Relationship between Pore Shapes and Mercury Porosimetry Curves as Revealed by a Random Pore Networks
Original language description
We developed a random pore network model that was a geometrical simplification of a macroporous medium. The network consisted of chambers interconnected by pore throats and had the same total porosity and external size as pellets of the real medium. Chamber volume and throat size distributions and network connectedness were derived from replicas of the porous medium. The replicas were obtained by means of three-dimensional stochastic reconstruction. Free network parameters involved chamber shape throatshape,and levels of spatial correlation between chamber and throat sizes and between adjacent chamber sizes. Then, we developed a simulator of mercury intrusion and withdrawal, which could handle the formation of mercury menisci in chambers and throats of our particular geometry. The simulator of mercury intrusion was based on the mechanism of invasion percolation.
