Abstract

A two-dimensional numerical model for convection-diffusion flow of multi- gases mixture through a multi-layered porous medium was developed with the aim of being used for evaluation of emissions of gases from landfills. The proposed model is based on the Boundary Element - Dual Reciprocity Method. In order to obtain an optimal performance of the proposed numerical scheme a subdomain decomposition approach was implemented. The model was applied to the problem of venting channels. From this analysis it is expected to find whether is is better to use one or two trenches within the considered length of the landfill, and the position
