Contaminant transport in sets on parallel finite fractures with fracture skins

摘要

Analysis of flow and transport in double/dual-porosity or fractured formations is a problem with important theoretical and practical applications. We present steady-state and transient solutions for solute transport in a finite system of parallel fractures with fracture skins. Solute transport in the fractures is by advection and hydrodynamic dispersion. Concentrations are attenuated by diffusion into the porous matrix. Radioactive decay and sorption in the skin, the matrix, and along the fracture walls are included. Our analysis extends previous studies by considering both finite fracture lengths and the effects of fracture skins.
