Porous media is a research area that focuses on the study of materials with interconnected void spaces, such as rocks, soils, and biological tissues. These void spaces allow for the flow of fluids, such as water, air, or gases, through the material. Researchers in this field study how fluids interact with porous materials, including phenomena like fluid flow, heat transfer, and mass transport. Applications of porous media research include understanding groundwater flow, designing filtration systems, enhancing oil recovery, and optimizing drug delivery systems.
