  1. 6. A study of turbulence and scalar mixing in a wall-jet using direct numerical simulation

    Författare :Daniel Ahlman; Arne V. Johansson; Lars-Erik Eriksson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningmekanik; Fluid mechanics; Strömningsmekanik;

    Sammanfattning : Direct numerical simulation is used to study the dynamics and mixing in a turbulent plane wall-jet. The investigation is undertaken in order to extend the knowledge base of the influence of the wall on turbulent dynamics and mixing. The mixing statistics produced can also be used to evaluate and develop models for mixing and combustion. LÄS MER

  3. 7. Development and results of the Swedish road deflection tester

    Författare :Peter Andrén; Anders Eriksson; Anders Lenngren; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Other engineering mechanics; Övrig teknisk mekanik;

    Sammanfattning : A project to construct a high-speed road deflection tester was initiated in the 1991. A mid-sized truck was used as a carrier for the first prototype. The results were promising and it was decided to build a full-size truck system. The new vehicle, based on a Scania R143 ML, was completed in 1997. LÄS MER

  4. 8. On-line time domain reflectometry diagnostics of medium voltage XLPE power cables

    Författare :Valentinas Dubickas; Roland Eriksson; Tord Bengtsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical engineering; Elektroteknik;

    Sammanfattning : Degradation of XLPE insulated power cables by water-trees is a primary cause of failure of these cables. The detection of water-trees and information about the severity of the degradation can be obtained with off-line measurement using dielectric spectroscopy. In many situations only a limited part of the cable may be degraded by the water-trees. LÄS MER

  5. 9. Sjötransporter och regional omvandling : Regleringen av den norrländska vintersjöfarten 1940-1975

    Författare :Martin Eriksson; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Norrland; Sweden; winter shipping; ice-breakers; decision-making; institutional framework; regulation; Economic history; Ekonomisk historia;

    Sammanfattning : This licentiate thesis investigates the decision-making process behind the regulation of winter shipping along the coast of the northern part of Sweden, the Norrland region, in the period 1940-1975. The licentiate thesis examines two aspects of this decision-making process. LÄS MER

  7. 10. Simulation of mechanical joining for automotive applications

    Författare :Johannes Gårdstam; Anders Eriksson; Kjell Simonsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Other materials science; Övrig teknisk materialvetenskap;

    Sammanfattning : Regarding the use of material, modern lightweight car bodies are becoming more and more complex than previous constructions. The materials nowadays are used for a more specific field of application and more high strength steels are used and also other materials like aluminium, stainless steel, reinforced polymers are used more frequent.
