Flow and reactive transport processes in porous media

[摘要] ENGLISH ABSTRACT: Flow and reactive transport of chemical species is a very common phenomenon that occursin natural and artificial systems. However in this study, the topic is related to acidmine drainage in the South African mining environment. Due to the hazards associatedwith acid mine drainage, prevention or treatment of mine effluent water before dischargingto receiving waters and other environments is a necessity. A new time-dependentmathematical model is developed for a passive treatment method, based on multi-scalemodelling of the coupled physico-chemical processes such as diffusion, convection, reactionsand filtration, that are involved in the treatment process. The time-dependentmodel is simulated on a two-dimensional domain using finite volume discretization toobtain chemical species distributions.
