Porous medium - Wikipedia
WebIn materials science, a porous medium or a porous material is a material containing pores (voids). [1] The skeletal portion of the material is often called the "matrix" or "frame". The pores are typically filled with a fluid ( liquid or gas ). The skeletal material is usually a solid, but structures like foams are often also usefully analyzed ...
