Abstract This paper presents a multiscale model developed for the modelling of multiphase flow in fractured reservoirs, particularly in coal seams during coalbed methane recovery (or carbon dioxide storage). The variation of gas content in the matrix induces a shrinkage/swelling of the material which is likely to affect the fractures and thus the permeability of the rock. In addition, the permeability is also sensitive to the effective stress evolution. In order to simulate the reservoir product...

Abstract A methodology for identifying and calibrating the material parameters for a coupled hydro-mechanical problem is presented in this paper. For validation purpose, a laboratory-based water infiltration test was numerically simulated using finite element method (FEM). The test was conducted using a self-designed column-type experimental device, which mimicked the wetting process of a candidate backfill material in a nuclear waste repository. The real-time measurements of key state variables...

1. Introduction Faced with the current environmental challenges about climate change and depletion of earth’s resources (UNEP/UNECE, 2016), the building sector needs to renovate its design practices and methods by taking into account economic, sanitary and comfort criteria. The development of materials that address these criteria and promotion of their use is put forward. Raw earth is one of these materials (Niroumand et al., 2017). Raw earth designates the earth used in construction unfired but...

Abstract Coal permeability is known to be affected by the sorption-induced strain. Indeed, coal swells with gas sorption and shrinks with desorption, which is likely to modify the cleat aperture and thus the permeability. Coal permeability evolution is crucially important for either Coalbed Methane production (CBM) or Carbon dioxide Capture and Storage (CCS). A model is developed at the scale of the fractures to take into account the hydro-mechanical couplings observed experimentally. It is impl...

It is well known that it is necessary to introduce a length scale parameter in a continuum damage mechanics model to correctly simulate strain localization. The second gradient model, a special case of kinematically enriched continua, considers an internal length parameter by taking into account the second-order derivatives of the displacements in the virtual power principle. In this paper, we show that the original second gradient finite element of Chambon and co-workers can present spurious os...

Le barrage de Youmban se situe dans le canton de Gorouol, departement de Tera (Region de Tillabery, Niger). Il appartient a la zone semiaride du Liptako-Gourma. Ses coordonnees geographiques sont : 14°48’7.80’’ de latitude N et 00°22’4.14’’ de longitude E. Les apports d’eau a ce barrage, proviennent des deux grandes rivieres temporaires localement connues sous les noms du Beli et du Gorouol. Depuis sa construction en 2004 ce barrage a connu une repetition de ruptures a l’emplacement de son organ...
