#Ansys Fluent Flow Through Porous Media Part 1/2 - YouTube

WebDec 7, 2024 · A medium or a material that has voids or pores or is filled with solid particles which let fluid pass through is called a porous medium. Porous media is a bidirectional concept. Whether it is isotropic (3D) or 1D, bidirectional means the flow can pass through opposite directions. Consolidated medium: Solid-body has internal pores. WebPorosity is an intrinsic property of every material. It refers to the amount of empty space within a given material. In a soil or rock the porosity (empty space) exists between the grains of minerals.
