In this study, COMSOL Multiphysics was used for the reliability evaluation for static chamber method at landfill sites. Static chamber method, which measures landfill gas emission fluxes, is widely used at landfill sites for the monitoring of greenhouse gas emission such as methane and carbon dioxide. The accuracy and the reliability of static chamber method are dependent on the measuring condition and the magnitude of the gas flux emitted from a landfill site. To investigate their effects on the accuracy and reliability of static chamber method, this study proposed the simulation model for the multicomponent gas advection-diffusion-reaction model.
