  2. 1. Numerical modeling of coupled thermo-hydro-mechanical processes in geological porous media

    Author : Fuguo Tong; Lanru Jing; Chin-Fu Tsang; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermo-hydro-mechanical processes; Porous geologicalmedia; Numerical modeling; FEM; Multiphase flow; Effective thermal conductivity; Water retention curve; Radioactive waste repositories; Bentonite; ; Geoengineering; Geoteknik;

    Abstract : Coupled Thermo-Hydro-Mechanical (THM) behavior in geological porous media has been a subject of great interest in many geoengineering disciplines. Many attempts have been made to develop numerical prediction capabilities associated with topics such as the movement of pollutant plumes, gas injection, energy storage, geothermal energy extraction, and safety assessment of repositories for radioactive waste and spent nuclear fuel.

  4. 2. Upscaling of Flow, Transport, and Stress-effects in Fractured Rock

    Author : Johan Öhman; Auli Niemi; Ove Stephansson; Robert W Zimmerman; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Hydrology; Upscaling; fractured media; flow; solute transport; thermo-hydro-mechanical processes; hybrid approach; continuum approximation; discrete fracture network; stochastic continuum; Hydrologi; Hydrology; Hydrologi;

    Abstract : One of many applications of geohydraulic modelling is assessing the suitability of a site to host a nuclear waste repository. This modelling task is complicated by scale-dependent heterogeneity and coupled thermo-hydro-mechanical (THM) processes. READ MORE

  5. 3. Fractured Rock Masses as Equivalent Continua - A Numerical Study

    Author : Ki-Bok Min; KTH; []
    Keywords : fractured rock masses; equivalent continuum; discrete fracture Network DFN ; Distinct Element Method DEM ; Finite Element Method FEM ; Nuclear Waste Disposal; Coupled Thermo-Hydro-Mechanical Processes;

    Abstract : In this thesis, fractured rock masses are treated asequivalent continua for large-scale analyses of rockengineering projects. Systematic developments are made for thedetermination of equivalent mechanical and hydraulic propertiesof fractured rock masses using a hybrid discrete fracturenetwork - distinct element method (DFN-DEM) approach.
