  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. Conditions for Industrial Symbiosis surrounding a hydrogen based steel industry

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

    Författare :Erland Nylund; [2023]
    Nyckelord :Industrial Symbiosis; H-DRI steelmaking; Industrial Symbiosis Networks; Waste management; Supplementary Cementitious Material SCM ; circular economy; Industriell symbios; H-DRI stålproduktion; Industriell Symbios-nätverk; restmaterialhantering; alternativa cementmaterial; SCM ; cirkulär ekonomi.;

    Sammanfattning : There is an ongoing transition to a more sustainable industry with lower climate impact. As part of this transition, the steel industry is expected to move from the conventional process for producing iron and steel using Blast Furnace (BF) and Basic Oxygen Furnace (BOF) processes, consuming large amounts of fossil fuels.

  4. 3. Promoting Circular Economy By Partial Replacement Of Cement With SCMs : A Review On Wood Ash

    M1-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Asal Salman; [2022]
    Nyckelord :Cement; Circular economy; Concrete industry; SCM; Wood ash;

    Sammanfattning : The European Commission adopted the first action plan for the transition to a circular economy in 2015. As a result, the concrete industry’s goal is for all concrete produced in Sweden to be climate neutral by 2045. LÄS MER

  5. 4. Accelerated Carbonation Of Cement Pastes And Mortars

    Kandidat-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Pejman Hajibabaei; [2022]
    Nyckelord :karbonatisering; accelerated carbonation; SCMs; cement paste; carbonation depth;

    Sammanfattning : Concrete structures have the largest surface area of all human made structures. Large surface area makes concrete capable to absorb CO2 from environment during its lifetime. It is estimated that concrete during its lifetime can absorb about 15-20% of CO2 which had produced in cement production. LÄS MER

  7. 5. Achieving a Collaborative Goal-oriented Planning Process : Exploring the Early Stages of Swedish National Transport Planning

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Signe Hanson Wallgren; [2022]
    Nyckelord :Collaborative planning; Wicked problems; Management by objectives; Transport planning; Environmental aspects; Environmental objectives; Strategic Choice of Measures; Sweden; Kollaborativ planering; Komplexa problem; Målstyrning; Transportplanering; Miljöaspekter; Miljömål; Åtgärdsvalsstudie; Sverige;

    Sammanfattning : The transport sector is facing a noticeable challenge to decrease its environmental and climate impacts, as well as to increase the possibility to achieve the objectives that are managing the societal development. Additionally, the early stages of transport planning are characterised by the participation of many stakeholders and that several areas of interest are affected, which entails that no distinct solution exist.
