Hierarchical Porosity - an overview ScienceDirect Topics

WebIn materials science, a porous medium or a porous material is a material containing pores (voids). 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 using concept of porous media. . … Web1 de fev. de 1992 · Semantic Scholar extracted view of "Dynamics of Fluids in Hierarchical Porous Media." by M.
