  1. 1. Thermal transients study for the ESS target helium cooling system

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Hannes Björk; [2022]
    Nyckelord :ESS; European Spallation Source; models; Modelica; system identification; sensors; cooling system; Technology and Engineering;

    Sammanfattning : The European Spallation Source (ESS) is going to be the worlds most powerful spallation source once in full operation. The neutrons used by scientists and engineers are spallated from a rotating wheel of wolfram, being bombarded by accellerated protons. LÄS MER

  4. 3. Svällande brandstopp i fasadsystem - En experimentell studie

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Johan Bengtsson; Alex Åkesson; [2021]
    Nyckelord :Fasad; luftspalt; brandstopp; fuktmättnad; rainscreen cladding; Technology and Engineering;

    Sammanfattning : Since many new techniques and new materials have been introduced in the construction of facades there is a need to better understand the behavior when exposed to a fire. Recent facade fires involving rainshield claddings have displayed major consequences regarding the personal safety of the occupants and towards an economic loss. LÄS MER

  5. 4. Characterization of the ethylene-vinyl acetate copolymer and the influencing parameters of the weld in intravaginal rings

    Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

    Författare :Ludwig Kaindl; [2020]
    Nyckelord :Ethylene-vinyl acetate; Intravaginal rings; DSC; Thermal properties EVA; Welding; Pharmaceutical Technology; Läkemedelsteknologi; Technology and Engineering;

    Sammanfattning : The aim of this thesis was to characterize the mechanical and thermal properties of three different ethylene vinyl acetate (EVA) polymers with varying vinyl acetate (VAc) content and to investigate the influential parameters when welding the polymer into intravaginal rings. A second purpose in this study was to compare two different produced EVA polymers with the same VAc content to find thermal and structural differences. LÄS MER

  7. 5. Construction of a Heat Transfer Rig based on Energy Balance for Rapid Production of Correlations for Additively Manufactured Geometries

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Joaquin Quesada Zeljkovic; [2019]
    Nyckelord :;

    Sammanfattning : This thesis has set the first milestones towards building a Nusselt number correlation that adapts to the current state of art designing and manufacturing processes at Siemens Industrial Turbomachinery AB, focusing on cooling mini-channels produced with Additive Manufacturing.  Additive manufacturing (AM), also known as 3D printing, is a gamechanger technology that has revolutionised manufacture and design know-how, bringing down production cost, time and waste.
