  2. 1. Suffusion of Glacial Till Dam Cores : An Experimental Investigation

    Author : Ingrid Silva; Jan Laue; Peter Viklander; Cristina Jommi; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Geoteknik; Soil Mechanics;

    Abstract : Suffusion, also called internal instability, is an internal erosion mechanism that occurs in embankment dams when fine-grained particles are washed out of the core soil matrix by seepage. Initiation of internal erosion depends mainly on three major factors: grain size distribution of the soil, stress conditions and hydraulic load; whilst its continuation depends of the filter properties.

  4. 2. Aerothermal Experimental Investigation of LPT-OGVs

    Author : Borja Rojo; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Experimental; Turbine Rear Structure; Aerodynamics; Wind Tunnel; CFD; Gas Turbine; Engine Exit Structure; Outlet Guide Vane; Heat transfer.; Turbine Exhaust Case; Turbine Rear Frame; Exit Guide Vane;

    Abstract : This thesis presents the design, commissioning, and experimental data of a newly built turbine facility at Chalmers University of Technology for investigating the ow in the engine exit structure (EES). The EES is the structure located downstream of the lowpressure turbine (LPT) in a jet engine. READ MORE

  5. 3. Deformations and stresses in welded pipes : numerical and experimental investigation

    Author : Lars Troive; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datorstödd maskinkonstruktion; Computer Aided Design;

    Abstract : In this dissertation, deformations and stresses in welded pipes have been studied both numerically and experimentally. The aim of this work has been to investigate and verify finite element models for simulation of the fabrications of two types of pipe joints. READ MORE

  6. 4. Plastic behaviour of steel : experimental investigation and modelling

    Author : Jonas Gozzi; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel Structures; Stålbyggnad;

    Abstract : This thesis deals with the plastic behaviour of steel. It comprises an investigation with focus on biaxial tests and constitutive modelling. Tests were performed on one stainless steel grade in two different strength classes, C700 and C850, as well as one extra high strength structural steel grade. READ MORE

  7. 5. Major leaching processes of combustion residues : characterisation, modelling and experimental investigation

    Author : Jinying Yan; KTH; []
    Keywords : ;

    Abstract : Characterising leaching behaviour provides ample evidence toidentify the majorleaching processes of combustion residues.Neutralisation and chemical weatheringgovern the leachingreactions and control the release of major, minor and traceelementsfrom combustion residues, and are thus considered to bethe major leaching processes.
