A STATISTICAL CHARACTERIZATION FOR POROUS MEDIA STRUCTURES
Main Article Content
Abstract
Some porous media structures may appear complicated at first glance. With proper treatments, these structures may be simplified and characterized for further analysis. In this paper, a method to statistically characterize the structure of a porous media is presented. Tomography images of a severely damaged nuclear reactor core are used as samples to develop the proposed method. It is found that the particle and void size distributions of the samples can be obtained. These distributions appear to be good representations of the damage degree of the corresponding locations. They may be fitted by the sum of standard beta distribution functions which are easier to use for a physical and mathematical modeling of such porous structure. It is expected that this method can also be applied to different types of porous structure in other applications.
