Landfill emission of gases into the atmosphere

摘要: Introduction - General considerations gas transport models numerical simulations of flow out a landfill boundary element method cell integration and dual reciprocity (DRM) nomenclature. Sanitary Landfills description gases production modelling. Fundamental Principles Conservation mass species i diffusive velocity flux governing equation heat generation transport. Boundary Element Formulation Single model multi model. Domain Decomposition on the DRM Approach Approximating functions in examples. The DRM-MD Integral Equation Method basic concepts approach BEM Solution for Design Trenches Multi-layered examples discussions.
