  1. 21. Near-Field Study of Multiple Interacting Jets : Confluent Jets

    Författare :Shahriar Ghahremanian; Bahram Moshfegh; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multiple interacting jets; confluent jets; axisymmetric round jet; Low Reynolds number jet; Particle Image Velocimetry PIV ; Laser Doppler Anemometry LDA ; Hot-Wire anemometry HWA ; RANS turbulence models; SST ? − ?; Low Reynolds ? − ?; Response Surface Method;

    Sammanfattning : This thesis deals with the near-field of confluent jets, which can be of interest in many engineering applications such as design of a ventilation supply device. The physical effect of interaction between multiple closely spaced jets is studied using experimental and numerical methods. LÄS MER

  3. 22. Edge Geometry Effects on Entry Phase by Forces and Vibrations

    Författare :Adnan Agic; Tomas Beno; Jan-Eric Ståhl; Mahdi Eynian; T.H.C. Childs; Högskolan Väst; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Entry; Cutting force; Cutting edge geometry; Acceleration; Production Technology; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

    Sammanfattning : Intermittent machining is in general strongly related to the large impacts in the entry phase and related vibrations. The influence of the impact forces and vibrations on the cutting process is dependent on workpiece material, structural properties of the tool-workpiece system, cutting edge geometries and cutting parameters.

  4. 23. Controlling Forced Response of a High Pressure Turbine Blade

    Författare :Jeff Green; Torsten Fransson; Robert Kielb; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering mechanics; Teknisk mekanik;

    Sammanfattning : Vibration induced High Cycle Fatigue (HCF) is a major consideration in designing gas turbines. Indeed, the Gas Turbine manufacturer must demonstrate that the vibration level of the turbomachinery blading is acceptably low, usually by using an engine strain gauge test. LÄS MER

  5. 24. Engineering and applications of surface displayed tyrosinase on Escherichia coli

    Författare :David Hörnström; Antonius J. A. van Maris; Joachim José; KTH; []
    Nyckelord :Bioteknologi; Biotechnology;

    Sammanfattning : The rise of biotechnology has provided a toolbox to deal with major challenges related to pollution and health. Microbial enzymes constitute powerful macromolecules with applications in environmental technology, and industrial and medical production. LÄS MER

  7. 25. A study on Electron Beam Melted Ti-6Al-4V

    Författare :Adnan Safdar; Hållfasthetslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ti-6Al-4V; Electron beam melting; Microstructures; Surface roughness; phase filed modelling.;

    Sammanfattning : The work presented in this dissertation is concerned with the microstructures and surface roughness of test slabs of Ti-6Al-4V produced by one of powder based Additive Manufacturing (AM) technique namely electron beam melting (EBM). The effects of process parameters of a EBM system and geometry factors of a EBM build such as slabs’ thickness and height etc. LÄS MER
