Collection of landfill gas by horizontal perforated wells is studied. The problem combines flow through porous media in the landfill and unobstructed pipe flow in the well. Respective analytical solutions to flow equations are used in an iterative numerical procedure to solve the coupled system. Realistic landfill input parameters confirm the feasibility of estimates obtained with the model. The study identifies flow control parameters and furnishes tools to evaluate surface flux and radius of influence for this type of well.

垃圾填埋气体流量：水平井收集

研究了水平射孔井收集垃圾填埋气。这个问题结合了垃圾填埋场中多孔介质的流动和井中畅通无阻的管道流动。在迭代数值程序中使用流动方程的相应解析解来求解耦合系统。现实的垃圾填埋场输入参数证实了用模型获得的估计值的可行性。该研究确定了流动控制参数并提供了工具来评估此类井的表面通量和影响半径。
