Numerical Methods for Contaminant Transport in Porous Media

摘要

The transport of contaminants in porous media is a complex process that may involve from one to three phases and possibly several components appearing in different phases based upon reservior conditions. Model equations for these flow regimes are described. All models can be put into the form of convection/diffusion/reaction equations coupled to mass balance and momentum balance equations. Discretization techniques that address aspects of conservation of mass and accurate and stable treatment of transport are discussed.
