 ABSTRACT

Kinetic mechanism and migration modeling form a theoretical basis of landfill gas resource utilization. To study the transferring law will provide theoretical support to landfill site design and landfill gas utilization. Based on systemic analysis of the kinetic mechanism, according to multiphase fluid seepage theory, a mathematical model to describe landfill gas and percolate flow was derived, and its numerical solution method was also given. The paper can provide a method to calculate landfill gas and percolate production and simulate their flow process.
