Nomsothermal multiphase flow of brine and gas through saline media - Olivella, Sebastià
[EN] A new formulation for the coupled analysis of thermo- hydro- mechanical problems in saline media is presented. The work ranges from the establishment of the mass, momentum and energy balance equations to its numerical solution by means advanced numerical techniques, including the derivation of some constitutive laws. The resulting computer program (CODE-BRIGHT) can be used to analyze real problems of sealing systems built with porous salt aggregates,
which was the original motivation of the work.
Metodología para la modelación hidrogeológica de medios fracturados - Martínez Landa, Lurdes
[EN] Low permeability fractured media (LFFM) can be viewed as consisting of a virtually impervious matrix transversed by more or less conductive fractures.
Experience dictates that a few of these concentrate most of the flow, this controlling the overall behaviour of the medium. Therefore, they need to be characterized for proper understanding of the system. Unfortunately, no widely accepted methodology is available to this end. In this context the objective of this thesis is three fold:
