  1. 1. Combustion of solid waste from wood-based ethanol production

    Författare :Gunnar Eriksson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

    Sammanfattning : The solid residue from wood-based ethanol production has a low ash content and high heating value, making it interesting for combustion applications, e.g. small-scale appliances and gas turbines. Combustion and gasification properties have been studied using thermogravimetric analysis (TGA) and differential thermal analysis (DTA). LÄS MER

  4. 3. Accelerator-driven systems : safety and kinetics

    Författare :Marcus Eriksson; Janne Wallenius; Hamid Aït Abderrrahim; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nuclear physics; Kärnfysik; Nuclear physics; Kärnfysik;

    Sammanfattning : The accelerator-driven system (ADS) is recognized as a promising system for the purpose of nuclear waste transmutation and minimization of spent fuel radiotoxicity. The primary cause for this derives from its accelerator-driven, sub-critical operating state, which introduces beneficial safety-related features allowing for application of cores employing fuel systems containing pure transuranics or minor actinides, thereby offering increased incineration rate of waste products and minimal deployment of advanced (and expensive) partitioning and transmutation technologies.

  5. 4. Resonant Waves in the Terrestrial Magnetosphere

    Författare :Tommy Eriksson; Lars Blomberg; Stephan Buchert; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Space physics; Rymdfysik;

    Sammanfattning : Waves in the mHz frequency range are a prominent feature in the terrestrial magnetosphere. In this frequency range the waves have wavelengths comparable to the lengths of the geomagnetic field lines. The waves are then standing waves along closed field lines with endpoints in the southern and northern ionosphere. LÄS MER

  7. 5. Aerolastic simulation of wind turbine dynamics

    Författare :Anders Ahlström; Anders Eriksson; Martin O. L. Hansen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Applied mechanics; wind turbine; aeroelastic modelling; rotor aerodynamics; structural dynamics; MSC.Marc; Teknisk mekanik; Engineering mechanics; Teknisk mekanik;

    Sammanfattning : The work in this thesis deals with the development of an aeroelastic simulation tool for horizontal axis wind turbine applications. Horizontal axis wind turbines can experience significant time varying aerodynamic loads, potentially causing adverse effects on structures, mechanical components, and power production. LÄS MER
