  1. 1. CFD investigation of a unit cell inside a Plate Heat Exchanger

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Mattias Ly; [2023]
    Nyckelord :Plate Heat Exchanger; CFD; Computational Fluid Dynamics; LES; Large Eddy Simulation; Periodic; Unit Cell; Technology and Engineering;

    Sammanfattning : A numerical investigation of the unit cell approach has been done to reduce the computational cost for CFD (Computational Fluid Dynamics) of plate heat exchangers (PHE) at Alfa Laval. The reduced cost would enable LES (Large Eddy Simulation) to be done which would give a more detailed and accurate insight into the flow and heat transfer processes of the PHE. LÄS MER

  3. 2. Energy demand and biogas production in rural areas : A case study in the Raqayapampa community in Bolivia

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

    Författare :Halvor Solheim Haugen; Noel Arancibia Holm; [2023]
    Nyckelord :;

    Sammanfattning : Improved access to energy can greatly improve living standards, and there are correlations between increased access to electricity and higher scores on both the Human Development Index (HDI) and the Educational Development Index (EDI). Increasing access to energy can also help decrease dependability on hazardous fuels and energy sources, such as firewood for cooking. LÄS MER

  4. 3. Thermal Investigation of the Green Revolution Energy Converter : A study on the heat transfer within the GREC in regards of temperature distribution and heat rate

    L3-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

    Författare :Wilma Fager; Maja Abrahamsson Bolstad; Emma Gustafsson; Emma Andersson; Matilda Eriksson; [2023]
    Nyckelord :GREC; Energy; Heat transfer; Heat rate; Temperature distribution;

    Sammanfattning : To reduce emissions, new technological solutions can be of use. One technology which is currently being developed is the Green Revolution Energy Converter, GREC. GREC is an engine with the aim to produce electricity from temperature gradients.  This project is part of a greater project that is divided in two with different focus areas. LÄS MER

  5. 4. CFD Analysis of Engine Room Temperature : CFD Analysis of Engine Room Temperature: Case study The Grange Castle Power Plant Project

    Master-uppsats, Högskolan i Gävle/Avdelningen för byggnadsteknik, energisystem och miljövetenskap

    Författare :William Wanli; [2023]
    Nyckelord : CFD Computational Fluid Dynamics; ventilation system; temperature; airflow; engine room.;

    Sammanfattning : Computational Fluid Dynamics (CFD) has emerged as an indispensable tool in various engineering fields, particularly in the design and optimization of HVAC systems in complex environments, such as engine rooms. This paper presents a comprehensive overview of CFD applications and focuses on the engine rooms of the Grange Castle Power Plant in Dublin, Ireland. LÄS MER

  7. 5. Produktion av el och värme med stirlingmotorer från deponigas : På Blåbergets avfallsanläggning

    Uppsats för yrkesexamina på grundnivå, Mittuniversitetet/Institutionen för kemiteknik

    Författare :Gustav Salomonsson; [2022]
    Nyckelord :Landfill gas; Stirling Engine; Electricity generation; Heat production; Deponigas; Stirlingmotor; Elproduktion; Värmeproduktion;

    Sammanfattning : Sundsvall Energi har ansvaret för den gamla deponin på Blåbergets avfallsanläggning strax västerut från Sundsvall. Mellan slutet av 1960-talet fram till och med 2008 har ca 2 miljoner ton avfall deponerats. Från denna deponi har det under en längre tid producerats stora mängder deponigas. LÄS MER
