Three-dimensional numerical simulation model of biogas production for anaerobic digesters

  title={Three-dimensional numerical simulation model of biogas production for anaerobic digesters},
  author={Bowei Wu and Eric Louis Bibeau and Kifle G. Gebremedhin},
A review of the modeling of biogas production from anaerobic digesters is first conducted. A three-dimensional numerical simulation model that predicts biogas production from a plug-flow anaerobic digester is developed. The model is based on the principles of continuity, energy, and species transport. A first-order kinetic model is used to predict the chemical reactions and BOD (Biological Oxygen Demand) in the digestion process. A userdefined function for computing the chemical source terms of… CONTINUE READING
