Numerical Simulation for Landfill Stabilization Process considering Degradation of Organic Chemical Compounds in Waste

Hiroyuki ISHIMORI[1]
[1]Ritsumeikan University, Kyoto, Kyoto, Japan

This presentation describes the numerical simulation model where gas/liquid two-phase porous media flow equations are coupled to multicomponent gas-phase transport and water-phase transport equations in COMSOL Multiphysics. This is done in order to predict the landfill stabilization process considering degradation of organic chemical compounds in waste.
