   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tracer experiments; solute transport in fractured rock; advection-diffusion experiments; repositories; equivalent flowrate.; Spårämnesexperiment; ämnestransport i bergssprickor; advektion och diffusionsexperiment; slutförvar; ekvivalent flöde.;

   Abstract : One way of taking care of spent nuclear fuel is to place it in a geological repository. In Sweden, a three-barrier system is planned. The system is based on encapsulating the fuel in copper canisters. These are surrounded by bentonite clay and buried under 500 m of bedrock. READ MORE

4. 2. Numerical Modelling of Self-Compacting Concrete Flow : Discrete and Continuous Approach

   Author : Annika Gram; Johan Silfwerbrand; Ali Farhang; Mette R. Geiker; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SCC; rheology; Simulation of Flow; Simulering; Flöde; Självkompakterande Betong; Reologi; Construction materials; Konstruktionsmaterial;

   Abstract : With the advent of Self-Compacting Concrete (SCC) that flows freely, under the soleinfluence of gravity, the wish for hassle-free and predictable castings even in complexcases, spurged the simulation of concrete flow as a means to model and predictconcrete workability. To achieve complete and reliable form filling with smoothsurfaces of the concrete, the reinforced formwork geometry must be compatible withthe rheology of the fresh SCC. READ MORE

5. 3. Thermal response tests : influence of convective flow in groundwater filled borehole heat exchanger

   Author : Anna-Maria Gustafsson; Jeffrey D. Spitler; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vattenteknik; Water Resources Engineering; VA-teknik; Urban Water Engineering;

   Abstract : The main objective of this doctorial thesis was to investigate how thermally induced movements in the groundwater (natural convective flow) may influence the heat transport in borehole and surrounding bedrock in a groundwater filled borehole heat exchanger system. The purpose was also to determine if thermal response tests could be used to detect the convective influence and the effect on evaluated heat transfer parameters, effective bedrock thermal conductivity and borehole thermal resistance.

6. 4. A study of hydroelastic fluid-structure interaction with application to immersed cantilevers

   Author : Johan Lorentzon; Strömningsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Partitioned Fluid-Structure; Blocked Gauss-Seidel; Jacobian-free Newton-Krylov methods; Incompressible fluid; Finite Strain; Total Lagrangian; Arbitrary Lagrange Euler method; Vector acceleration;

   Abstract : This study presents an approach for partitioned fluid-structure interaction (FSI) applied to large structural deformations, where an incompressible turbulent solver is combined with a structural solver. The implementation is based upon two different open-source libraries by using MPI as a parallel communication protocol, the packages deal. READ MORE
