Heterogeneous media is a research area that focuses on the study of materials or substances that are composed of different components or phases. These components can vary in terms of their physical or chemical properties, such as their composition, structure, or behavior. The study of heterogeneous media typically involves investigating how these different components interact with each other and how they affect the overall properties and behavior of the material as a whole. Research in this area can encompass a wide range of topics, including the study of composites, porous materials, multiphase fluids, and other complex materials systems. The goal of studying heterogeneous media is often to better understand their properties and behavior, and to develop new materials with tailored or improved properties for specific applications.
