Hydrodynamic Dispersion in Porous Media

  • Ne-Zheng Sun

Abstract

When fluid flows through the interconnected voids and passages of a porous medium, the walls of these voids and passages form many small tunnels, and the fluid flows inside them. The study of physical phenomena in a porous medium on such a scale (pore scale) is called the microscopic method. Due to the complexity of the micro-geometry of porous media, it is unrealistic to study the details of the flow on this scale. Therefore, one has to describe the flow phenomena in porous media on a macroscopic rather than microscopic basis. The spatial average method is a way to transfer properties of porous media from the microscopic level to the macroscopic level.
