Landfill Emission of Gases into the Atmosphere: Boundary Element Analysis

In this volume a mathematical model for the solution of convection-diffusion flow of a mixture of gases in a multi-layer porous media is described. This is applied to the problem of gases generation and migration inside a landfill and their release into the atmosphere.
The authors present two different boundary element formulations, based upon the dual reciprocity method (DRM), to transform the resulting domain integrals into surface integrals. The first method treats the whole problem domain as a single one, while the second, the dual reciprocity method – multi-domain decomposition (DRM-MD), divides the initial domain into a large number of subdomains.
