- Abstract
- Mercury intrusion porosimetry is a widely used method for measuring the pore-size distribution of porous materials. This paper describes an algorithm that has been developed that simulates mercury intrusion into a two-dimensional porous material. The simulation can be implemented on model sturctures or on micrographs of real porous materials. Using a burning algorithm, the critical pore diameter for mercury connectivity can be directly computed and studied as a function of microstructure. The point at which the intruding mercury becomes continuous is found to occur at the inflection point of the cumulative intrusion curve, in agreement with recent experimental results.
