  1. 21. Pyrolysis of biomass in fluidized-beds: in-situ formation of products and their applications for ironmaking

    Författare :Pelle Mellin; Weihong Yang; Blasiak Wlodzimierz; Gerrit Brem; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biomass; Pyrolysis; Fluidized bed; CFD; Blast furnace; Teknisk materialvetenskap; Materials Science and Engineering;

    Sammanfattning : The iron and steel industry emitted 8 % of all CO2 emissions in Sweden, 2011. Investigating alternative energy carriers is the purpose of this thesis. By pyrolyzing biomass, an energetic solid, gaseous and liquid (bio oil) fraction is obtained. LÄS MER

  3. 22. Biological Production of Hydrogen and Methane: Process Evaluation and Design through Modeling

    Författare :Mattias Ljunggren; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biological hydrogen production; dark fermentation; photofermentation; process simulation; economic evaluation; gas upgrading; anaerobic digestion;

    Sammanfattning : A great deal of research is being carried out on the biological production of hydrogen and methane. However, little effort has been devoted to studying the technical and economic feasibility of these processes. LÄS MER

  4. 23. Computational Models of Adhesively Bonded Joints

    Författare :Peter Schmidt; Anders Klarbring; Ulf Stigh; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; adhesively bonded joint; asymptotic expansion; finite element; damage mechanics; Engineering mechanics; Teknisk mekanik;

    Sammanfattning : Simulations using the Finite Element Method (FEM) play an increasingly important role in the design process of joints and fasteners in the aerospace industry. In order to utilize the potential of such adhesive bonding, there is an increasing need for effective and accurate computational methods. LÄS MER

  5. 24. Aircraft Design Automation and Subscale Testing : With Special Reference to Micro Air Vehicles

    Författare :David Lundström; Petter Krus; Jean- Marc Moschetta; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : This dissertation concerns how design automation as well as rapid prototyping and testing of subscale prototypes can support aircraft design. A framework for design automation has been developed and is applied specifically to Micro Air Vehicles (MAV). LÄS MER

  7. 25. Manufacturing system data management and development : towards a STEP compliant reference model for manufacturing

    Författare :Mattias Larsson; Torsten Kjellberg; Anders Dannstedt; KTH; []
    Nyckelord :Information Management; Industrial Engineering; Collaborative Engineering;

    Sammanfattning : Collaborative engineering assumes a common understanding of the domain. To make joint decisions the engineers must have a common language to start from. Standards such as STEP may be used to communicate engineering data but to speak about information integration and interoperability there must be ways to expose and share concepts as well. LÄS MER
