porous media flow

Porous media flow refers to the movement of liquids or gases through materials that contain tiny pores or spaces, such as soil, rocks, or sponges. These pores allow fluids to pass, but the flow rate depends on the material’s properties, like pore size and connectivity, as well as the fluid’s characteristics. This concept is important in fields like groundwater movement, oil recovery, and filtration. Essentially, it describes how fluids travel through complex, often irregular pathways within solid materials, governed by principles of physics and fluid dynamics.
