  1. 1. Experimental and Numerical Investigations of Confluent Round Jets

    Författare :Klas Svensson; Bahram Moshfegh; Patrik Rohdin; Bengt Sundén; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Confluent jets; Multiple jet array; Jet interactions; Confluent Core Zone CCZ ; Particle Image Velocimetry PIV ; Laser Doppler Velocimetry LDA ; Computational Fluid Dynamics CFD ; Response Surface Methodology;

    Sammanfattning : Unconfined multiple interacting confluent round jets are interesting from a purely scientific point of view, as interaction between neighboring jets brings additional complexity to the flow field. Unconfined confluent round jets also exist in various engineering applications, such as ventilation supply devices, sewage disposal systems, combustion burners, chemical mixing or chimney stacks.

  3. 2. Sampling and Analysis of Tars by Means of Photo Ionization Detection and Solid Phase Micro Extraction

    Författare :Mozhgan Ahmadi Svensson; Klas Engvall; Wiebren de Jong; KTH; []
    Nyckelord :;

    Sammanfattning : Gasification of biomass will likely play an important role in the production of energy and chemicals in a future sustainable society. However, during gasification impurities, such as tars, will be formed. Tars may cause fouling and blockages of equipment downstream the gasifier. LÄS MER

  4. 3. Konstruktionen av framtidens stad : Arkitekttävlingar om bostäder och stadsdelar i Sverige 1989-2003

    Sammanfattning : The aim of this thesis is to show what values affect visions expressed in architectural competitions about housing and town planning in Swedish cities between 1989 and 2003. Four questions have guided the study: the changes that take place in the competition process; the social and spatial components and relations future neighborhood are put together of; the qualities that architectural competitions take into account; and the kind of urbanity the competitions lead to if the proposals are realised.
