[hal-01258643] Mathematical modeling and numerical simulation of a bioreactor landfill using Feel++

In this paper, we propose a mathematical model to describe the functioning of a bioreactor landfill, that is a waste management facility in which biodegradable waste is used to generate methane. The simulation of a bioreactor landfill is a very complex multiphysics problem in which bacteria catalyze a chemical reaction that starting from organic carbon leads to the production of methane, carbon dioxide and water. The resulting model features a heat equation coupled with a non-linear reaction equation describing the chemical phenomena under analysis and several advection and advection-diffusion equations modeling multiphase flows inside a porous environment representing the biodegradable waste. A framework for the approximation of the model is implemented using Feel++, a C++ open-source library to solve Partial Differential Equations. Some heuristic considerations on the quantitative values of the parameters in the model are discussed and preliminary numerical simulations are presented.

[hal-01082527] Diffuse Optical Tomography For Tumour Detection Diffuse Optical Tomography For Tumour Detection

Time-resolved diffuse optical tomography aims to reconstruct images for internal parts of a body (diffusive objects owning one or several inclusions, small animals, ...) from its boundary measures. This poster gives an overview of the experimental setup created by the ICube/IMIS team and the mathematical model used for the reconstruction. Numerical results are obtained using FEEL++, a C++ library for finite element methods.
