多孔材料是一种由相互贯通或封闭的孔洞构成网络结构的材料,具有相对密度低、比强度高、比表面积高、重量轻、隔音、隔热和渗透性好等特点,已经广泛应用于航空航天、原子能研究、石化、冶金、机械、医药、环保等行业,并带来了可观的经济和社会效益。流体在多孔材料内部的流动特性研究是多孔材料研究的重要组成部分。本文简要介绍了多孔材料内流体流动特性的研究现状,主要对未来研究的发展方向进行了展望。
Porous material is a kind of material which is formed by interpenetrating or closed holes to form a network structure and has the characteristics of low relative density, high specific strength, high specific surface area, light weight, sound insulation, heat insulation and permeability and the like, and has been widely used in aviation Aerospace, atomic energy research, petrochemical, metallurgy, machinery, medicine, environmental protection and other industries, and brought considerable economic and social benefits. The study of fluid flow in porous materials is an important part of porous materials research. In this paper, the research status of fluid flow in porous materials is briefly introduced, and the future development of the research is forecasted.
