Abstract

The most common method of waste disposal in North America is the use of landfills. Landfill gas refers to the hazardous emissions produced by the waste in a landfill. Landfill gas needs to be controlled, which is done by extracting the gas through wells placed horizontally or vertically and then removing it from the area. Predicting the effect of a change in the function of a single well on the other wells in the landfill is very important to the design and operation of a landfill. The integrated normal flux between cells is an important parameter for a prediction model of this type. This is because the flux is equal to the difference in production of the two wells in question, which is a very easy thing to measure in the field. The effect of asymmetry on the landfill gas flow field in configurations with multiple suction points placed side by side or stacked was determined. The flux was found to have quite simple dependencies on the relative suction strengths of other cells in close proximity. As such, the proposed models would be easy to set up in many different configurations.

Effects of Asymmetry in Landfill Gas Flow

The most common method of waste disposal in North America is the use of landfills. Landfill gas refers to the hazardous emissions produced by the waste in a landfill. Landfill gas needs to be controlled, which is done by extracting the gas through wells placed horizontally or vertically and then removing it from the area. Predicting the effect of a change in the function of a single well on the other wells in the landfill is very important to the design and operation of a landfill. The integrated normal flux between cells is an important parameter for a prediction model of this type. This is because the flux is equal to the difference in production of the two wells in question, which is a very easy thing to measure in the field. The effect of asymmetry on the landfill gas flow field in configurations with multiple suction points placed side by side or stacked was determined.
