垃圾填埋气迁移规律的数值模拟研究

Research on numerical simulation of landfill gas transfer law of junk

用CFD软件FLUENT建立了填埋气迁移的三维多孔介质模型,对填埋场覆盖层、抽气井负压、填埋场周边土壤等对填埋气迁移的影响规律进行了模拟研究,为科学有效的收集利用填埋气奠定基础。

The paper indicates to establish three-dimension porous medium model of landfill gas transfer by using CFD software FLUENT,and has the simulation research on the influential law,including the landfill coating,the pumping negative pressure and the landfill surrounding soil,so as to lay the foundation for applying landfill gas in a scientific and effective way.
