%X In order to enhance the production of biogas and to
study the thermal behavior of waste, a numerical study of fluid flows and heat
transfers within household waste was developed to predict the distributions of
thermal fields.</span><span style=\"font-family:&quot;\"> The mathematical model is based on the conservation
of mass and energy equations. The resulting system of equations is discretized
using the finite volume method and solved using the Thomas algorithm. The
results of the model studied are compared with the numerical and site
measurements results from other authors. </span><span style=\"font-family:&quot;\">The
results have been found to be in good agreement</span><span style=\"font-family:&quot;\">. The results
show that the mathematical model is able to reproduce the thermal behavior in
anaerobic phase in landfills. The isotherms revealed that temperatures are
lower in the upper part of the waste cell, very high in the core and decrease
slightly in the bottom of the cell due to the biodegradation of waste.
