  1. 1. Biochar and district heating : The path to negative emissions

    Kandidat-uppsats, Uppsala universitet/Institutionen för samhällsbyggnad och industriell teknik

    Författare :Amanda Widlund; Thomas Norström; William Isaksson; Andreas Andersson; [2023]
    Nyckelord :biochar; pyrolysis; climate impact; carbon sink; district heating;

    Sammanfattning : Uppsala Kommun is developing a new city district called Sydöstra staden (SÖS) as an innovative and transformative city district. A technical supply system that aligns with the district’s goals is pyrolysis. Pyrolysis is a process where biomass is heated without the supply of oxygen. LÄS MER

  2. 2. On Modelling a Fighter Aircraft Fuel System as a Heat Sink

    Master-uppsats, Linköpings universitet/Fluida och mekatroniska system

    Författare :Mimar Youssef; [2023]
    Nyckelord :Fuel system; fighter aircraft; heat sink; modelling; modelica;

    Sammanfattning : This thesis presents a simulation study on the thermal performance of the fuel systemin a fighter aircraft. The main objective is to investigate the potential utilization of thefuel system as a heat sink and explore various operational aspects that can enhance itsperformance. LÄS MER

  3. 3. Adjoint optimization of a liquid-cooled heat sink

    Master-uppsats, KTH/Teknisk mekanik

    Författare :Roven Pinto; [2023]
    Nyckelord :Adjoint method; topology optimization; porosity; OpenFOAM;

    Sammanfattning : Improving the design of flow channels in a liquid-cooled heat sink is critical for boosting the capabilities of electronic components as well as reducing energy usage by the pump. This work explores the use of topology optimization to minimize the pressure difference across a heat sink and consequently, the energy used to supply the liquid. LÄS MER

  4. 4. Bluegreengrey (BGG) solution for future climate and flood-resilient urban drainage network by enhancing the natural hydrological cycle

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Adnan Asif Rifat; [2023]
    Nyckelord :Bluegreengrey; Sustainable stormwater; Basement flooding; Urban flooding; Pipe Network; BGG; Climate change; Hydrology; Mike .; Technology and Engineering;

    Sammanfattning : A loop of urbanization, increasing impervious surface in urban areas, increasing temperature, rainfall, surface runoff and flooding, and lack of new spaces have been adding challenges to urban drainage systems for decades. The climate change impacts are exposing the existing vulnerable conventional urban drainage systems to more challenges in the future. LÄS MER

  5. 5. Integration of an industrial heat pump for a TES-based power-to-heat system : A techno-economic assessment

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

    Författare :Cristian Contreras Aramayo; [2023]
    Nyckelord :Heat; electricity; industrial heat pump; power-to-heat;

    Sammanfattning : This work aims to investigate the potential electricity savings, as well as the potential decrease in LCoH and OPEX, that an integration of an industrial heat pump can have on a molten salt-based power-to-heat system with integrated thermal energy storage. The original system uses an electric heater to heat up molten salt, which acts as the heat transfer fluid of the system, from which heated steam can be produced and delivered at the output. LÄS MER
