Abstract:The degradation of solid waste in landfills results in the coupled migration of gas and leachate through the pore spaces in waste material. The existing analytical methods cannot be used to obtain a solution for the gas–leachate coupled migration problem. This study used the differential quadrature method to solve the gas and leachate phase continuity equations considering the effect of the gas–leachate coupling. The calculation results were verified based on the calculated data of previous studies. The result… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
