  1. 1. Study case: The water-cooling effect on floating photovoltaic plants performance

    Master-uppsats, KTH/Energiteknik

    Författare :Alice Dragon; [2024]
    Nyckelord :Solar photovoltaic; Floating photovoltaic; Performance analysis; Thermal loss; Panel Efficiency; Cooling effect; Solceller; Flytande solceller; Prestandaanalys; Termisk förlust; Panelens effektivitet; Kylande effekt;

    Sammanfattning : Floating solar technology is relatively new, and it comes with its own set of challenges and opportunities. This master thesis focuses on understanding how Floating Photovoltaic (FPV) projects perform compared to Ground-Based Photovoltaic (GPV) projects, in specific weather conditions. LÄS MER

  3. 2. The effect of recycling and processing routes on recrystallization in a secondary 3xxx aluminium alloy

    Master-uppsats, Jönköping University/JTH, Material och tillverkning

    Författare :Anton Rolseth; [2023]
    Nyckelord :Aluminium alloys; sheet metal forming; grain boundary segregation; recrystallization; Zener pinning; casting; rolling;

    Sammanfattning : Aluminium alloys have the possibility to be infinitely recycled. By only generating 5% of the emissions compared to primary aluminium, great CO2 savings can be made. One of the issues in manufacturing components entirely from post-consumer scrap is the presence of trace elements and impurities. Such elements can be Fe, Cu, Cr, P and Pb. LÄS MER

  4. 3. Effect of Trace Elements on the Particle Size of Magnesium Silicide in Aluminium Extrusion : The Use of Thermo-Calc and DICTRA in order to Produce Aluminium more Efficiently

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :Gustav Boustedt; Johan Alexander Valentin Nygren; Gustav Strandgård; [2023]
    Nyckelord :Thermo-Calc; DICTRA; simulations; EN AW 6082; extrusion; particle precipitation; Mg2Si; sustainable; trace elements; aluminium;

    Sammanfattning : This project is a feasibility study for Hydro Extrusion Sweden AB, a company that produces extruded aluminium profiles. The main purpose of this project was to analyse the difference of Mg2Si particle sizes in aluminium alloys when varying parameters, such as cooling rate and composition, in aluminium extrusion, particularly the EN AW 6082 alloy.

  5. 4. Data Centres as Prosumers: A Techno-Economic Analysis

    Master-uppsats, Uppsala universitet/Institutionen för materialvetenskap

    Författare :Jeremy Ericsson Sintong; [2023]
    Nyckelord :Data Centres; Prosumers; Techno-Economic Analysis; Waste Heat Recovery; District Heating; Heat Supply; Air-Cooled Data Centre;

    Sammanfattning : Rapid growth of digitalization has urged Data Centres (DC) to be more energy efficient by recovering waste heat from server racks that would otherwise be wasted. This techno-economic study is focused on upgrading low temperature waste heat from typical Air-Cooled DC for District Heating Network (DHN) market in Stockholm region. LÄS MER

  7. 5. Computational investigation of the feasibility touse solid neon moderation for GBAR

    Master-uppsats, Stockholms universitet/Fysikum

    Författare :Lars Gehrmann; [2023]
    Nyckelord :;

    Sammanfattning : The main goal of the GBAR (Graviational Behaviour of Antihydrogen at Rest) experiment is to investigatethe gravitational effect on antimatter by measuring the classical free fall of an antihydrogen atom. The requiredpositrons are created by pair production inside a tungsten target and are moderated using a tungsten mesh. LÄS MER
