Pore-network research focuses on studying the geometry and connectivity of the pore spaces within porous materials, such as rocks, soils, and ceramics. This research area aims to understand how fluids flow and transport within these porous materials, as well as how different properties, such as porosity, permeability, and capillary pressure, affect the behavior of fluids within the pore network. Pore-network modeling and simulation are common techniques used in this research area to analyze and predict fluid flow and transport in porous materials. Overall, pore-network research is essential for various applications in geosciences, engineering, environmental science, and material science.
