  2. 21. On Radiative Heat Transfer Modeling with Relevance for Combustor and Biomass Furnaces

    Author : Mehdi Bahador; Värmeöverföring; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; termodynamik; fluiddynamik; plasma; Thermal engineering; applied thermodynamics; Termisk teknik; plasmas; Gaser; Thermal Radiation; Scattering; Heat load; Gases; fluid dynamics; Biomass Furnaces; framdrivningssystem; Motorer; Motors and propulsion systems;

    Abstract : Thermal radiation sometimes is the dominating heat transfer mode in combustion chambers and furnaces and therefore in the design of many relevant industrial facilities prediction of it is necessary. During previous years many research efforts in the radiative heat transfer field have originated and many methods and models from simple to complex have been developed. READ MORE

  4. 22. Experimental methods of neutron diagnostics and fast ion physics for fusion devices

    Author : Andrea Sperduti; Marco Cecconello; Massimo Nocente; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fysik med inriktning mot tillämpad kärnfysik; Physics with specialization in Applied Nuclear Physics;

    Abstract : Measurements of the neutron emission resulting from nuclear fusion reactions provide an abundance of information on the underlying spatial, temporal and energetic distributions of reacting ions and how they are affected by a wide range of MagnetoHydroDynamic (MHD) instabilities.This thesis focuses on studies of the neutron emission and fast ion physics at the Mega Ampere Spherical Tokamak (MAST), its upgrade MAST-U, the Joint European Torus (JET) and the Divertor Tokamak Test (DTT).

  5. 23. Deposition of Al-doped ZnO films by high power impulse magnetron sputtering

    Author : Martin Mickan; David Horwat; Ulf Helmersson; Aline Rougier; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Transparent conducting oxides (TCOs) are an important class of materials with many applications such as low emissivity coatings, or transparent electrodes for photovoltaics and flat panel displays. Among the possible TCO materials, Al-doped ZnO (AZO) is studied due to its relatively low cost and abundance of the raw materials. READ MORE

  6. 24. Solar cavity receiver design for a dish-Stirling system

    Author : Jorge Garrido Gálvez; Björn Laumert; Uwe Gampe; KTH; []
    Keywords : Concentrating Solar Power; Solar receiver; Solar simulator; Uncertainty analysis; Monte Carlo ray tracing; Experimental validation; Coatings; System modeling; Structural analysis; Creep damage; Thermal stress; Cavity receiver design; Energy Technology; Energiteknik;

    Abstract : The growing concern for the climate change has led to an increasing research effort in renewable energy technologies in order to achieve a more sustainable electricity production. Concentrating Solar Power (CSP) is identified as a promising technology to deal with part of the future electricity production. READ MORE

  7. 25. Nano- and mesoscale morphology evolution of metal films on weakly-interacting surfaces

    Author : Bo Lü; Kostas Sarakinos; Peter Münger; Thomas Michely; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Thin films are structures consisting of one or several nanoscale atomic layers of material that are used to either functionalize a surface or constitute components in more complex devices. Many properties of a film are closely related to its microstructure, which allows films to be tailored to meet specific technological requirements. READ MORE
