poregeometri

Pore geometry refers to the physical characteristics and spatial arrangement of pores within a porous material. It encompasses aspects such as pore size, shape, connectivity, tortuosity, and distribution. Understanding pore geometry is crucial in various scientific and engineering disciplines because it directly influences the material's macroscopic properties, particularly its transport phenomena.

For instance, in geosciences, pore geometry dictates fluid flow and storage capacity in rocks, impacting hydrocarbon reservoir performance and groundwater hydrology. In materials science, the pore structure of ceramics, filters, or catalysts determines their permeability, surface area, and reactivity. Similarly, in biological tissues, the intricate pore networks within bones or cell membranes play vital roles in nutrient transport and structural integrity.

Quantifying pore geometry often involves techniques like microscopy (e.g., scanning electron microscopy), mercury porosimetry, gas adsorption, and X-ray computed tomography. Analyzing these geometric features allows researchers to predict and optimize material behavior for specific applications, such as improving filtration efficiency, enhancing catalytic activity, or understanding drug delivery mechanisms. The complexity and variability of pore geometry are significant challenges in accurately modeling and predicting the behavior of porous media.
