Semi-aerobic landfill has interesting structure that passively provides the atmospheric oxygen into landfilled waste due to the heat convection generated by the decomposition of landfilled waste. There are limited studies on the mechanisms of the oxygen transport. This paper presents the governing equations and parameter estimation methods for the numerical simulation of the gas fluid flow and thermal and reactive transport in landfill.
