  1. 1. Investigation of fuel and water injection in gas turbine combustion : Evaluate the methodologies available in Star CCM+ for modeling of water injection in simplified combustor using liquid and gas fuels

    Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

    Författare :Sanger Shinwari; [2023]
    Nyckelord :Diesel and Methane fuel combustion; FGM combustion model; Lagrangian multiphase modelling; Inert Stream; Water injection; STAR CCM ;

    Sammanfattning : The negative impact of gas turbine emissions on the environment and human health is a growing concern. Recent studies suggest injecting water into the combustion process effectively reduces emissions and increases power output. However, this approach presents new challenges that need to be thoroughly investigated. LÄS MER

  3. 2. Vattenrening i textilåtervinningsindustri : Reducering av nonylfenol, bromerade flamskyddsmedel och sulfat i re:newcells processvatten

    M1-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Klara Undin; [2020]
    Nyckelord :ozonering; MBBR; jonbyte;

    Sammanfattning : Kläder och textilier produceras och konsumeras i allt högre grad med stor påverkan på miljö, klimat och jordens resurser som följd. En attraktiv lösning på det är återvinning av kläder, vilket företaget re:newcell gör. LÄS MER

  4. 3. Comparing a full scale test with FDS, FireFOAM, McCaffrey & Eurocode

    Uppsats för yrkesexamina på grundnivå, Luleå tekniska universitet/Byggkonstruktion och brand

    Författare :Erik Edin; Mattias Ström; [2019]
    Nyckelord :FDS; FireFOAM; OpenFOAM; Performance-Based Design; Localized fire.;

    Sammanfattning : In the rapidly growing field of CFD-calculations (Computational Fluid Dynamics), companies and organizations are bringing forth new tools, tools that display an image of a given fire scenario. These tools are developed because they provide time efficiency as well as a sustainable economic approach. LÄS MER

  5. 4. HYDROGEN-FIRED GAS TURBINE FOR POWER GENERATION WITH EXHAUST GAS RECIRCULATION : Emission and economic evaluation of pure hydrogen compare to natural gas

    Master-uppsats, Mälardalens högskola/Framtidens energi

    Författare :Nemir Gibrael; Hamse Hassan; [2019]
    Nyckelord :harmful emission; natural gas; fuel reforming process; hydrogen fired gas turbine; exhaust gas recirculation; techno-economic analysis;

    Sammanfattning : The member states of European Union aim to promote the reduction of harmful emissions. Emissions from combustion processes cause effects on human health and pose environmental issues, for example by increasing greenhouse effect. LÄS MER

  7. 5. Assessment of thermal radiation arithmetic's for jet flames : A study involving generic calculation methods concerning radiation from jet flames with the purpose to determine the safety distance for flame effects

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Anne Lee Anderson; [2018]
    Nyckelord :Jet flame; view factor; incident radiation; radiation temperature; safety distance;

    Sammanfattning : Jet flames are commonly used as flame effects in pyrotechnical shows, and are also a possible risk in industries that uses pressurised flammable gas. For these users it is important to  make fire safety engineering calculations to minimise the risks. This project focus on jet flames that are used in pyrotechnic shows where, e.g. LÄS MER
