  1. 1. Stability analysis of a large span timber dome

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Avdelningen för Konstruktionsteknik

    Författare :Markus Herrström; Gustav Fredriksson; [2017]
    Nyckelord :Timber; Glulam; Dome; Instability; Buckling; FEM; Non-Linear; Imperfection; Creep; Settlements; Geodesic; Kiewitt; Abaqus; Stability; Technology and Engineering;

    Sammanfattning : The aim of this thesis is to study the feasibility of building a timber dome with a span of 300 metres, concerning elastic stability. The load-bearing members were modelled with the properties of glued laminated timber GL30c with the dimensions 0.8×1.6 m2. LÄS MER

  3. 2. Numerical study of surface heat transfer enhancement in an impinging solar receiver

    Master-uppsats, Uppsala universitet/Fasta tillståndets fysik

    Författare :Lifeng Li; [2014]
    Nyckelord :Jet impingement; Computational fluid dynamics CFD ; Conjugate heat transfer; Ribbed surface; Solar receiver;

    Sammanfattning : During the impinging heat transfer, a jet of working fluid, either gas or liquid, will besprayed onto the heat transfer surface. Due to the high turbulence of the fluid, the heat transfer coefficient between the wall and the fluid will be largely enhanced. LÄS MER

  4. 3. Live 3D-TV Streaming

    Kandidat-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Författare :Bishal Neupane; Pooya Moazzeni; [2012]
    Nyckelord :3D-TV; autostereoscopic; live; streaming; networks; communications;

    Sammanfattning : The world is not flat as a pancake. It has height, width and depth. So we should see it even on TV. So far we cannot see three-dimensional programs directly into our TVs. LÄS MER

  5. 4. Heat Transfer Correlations for Gas Turbine Cooling

    Magister-uppsats, Institutionen för konstruktions- och produktionsteknik

    Författare :Jenny Sundberg; [2006]
    Nyckelord :gas turbine; internal cooling; ribbed channels; matrix; impingement;

    Sammanfattning : A first part of a ”Heat Transfer Handbook” about correlations for internal cooling of gas turbine vanes and blades has been created. The work is based on the cooling of vanes and blades 1 and 2 on different Siemens Gas Turbines. LÄS MER
