  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

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

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

    Abstract : 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. READ MORE

  3. 2. Model Predictive Urea Dosing Control Strategy for Heavy-Duty Diesel Vehicles

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Mathias Schmekel; [2023]
    Keywords : Model predictive control; Selective catalytic reduction; Nitrogen oxides; Modell-prediktiv reglering; Selektiv katalytisk reduktion; Kväveoxider;

    Abstract : Stricter requirements on the reduction of Nitrogen Oxides (NOx) in the emissions of heavy-duty diesel vehicles drives development for more efficient aftertreatment systems. An ammonia covered catalyst is one of the most successful technologies in reducing NOx by converting it into the harmless byproducts water and nitrogen. READ MORE

  4. 3. 3D CFD Simulations of Hydrogen Engine Combustion

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Hao Liu; [2023]
    Keywords : Technology and Engineering;

    Abstract : With the trend of decarbonization, the transport sector is exploring possibilities of fossil fuel free solutions. Hydrogen can be a potential fuel for future engine applications. In this work, the concept of H2 HPDI is investigated, where a pilot diesel injection ignites the hydrogen jet. READ MORE

  5. 4. Techno economic assessment of CCUS for a biogas facility in Sweden : Evaluating the economic feasibility for three CCUS concepts

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Tobias Johansson; Markus Knutsson; [2022]
    Keywords : CCS; CCU; CCUS; Biogas; Biologic methanation; Negative emissions; TEA; Techno economic assessment.;

    Abstract : Many countries strengthen their commitments to reduce greenhouse gas emissions to limit climate change and meet the Paris Agreement (Masson-Delmotte et al., 2019). Commitments include achieving net-zero emissions or in some cases even negative emissions (Government offices of Sweden, 2020a; United Nations, 2021a). READ MORE

  6. 5. Automatic detection of the fuel composition in a Diesel Engine : Identifying fuel composition in the fuel system of a combustion engine and optimising for computational complexity

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Andree Hultgren; [2021]
    Keywords : Fuel Detection; Machine Learning; Feature Selection; Computational Complexity; Bränsledetektering; Maskininlärning; Paremeterval; Beräkningskomplexitet;

    Abstract : The transportation industry is responsible for 26% of all emission of greenhouse gases in the European Union. Many steps are being taken to minimise greenhouse gas emissions. The most effective way to reduce the emission of greenhouse gases is by transitioning to biofuels. READ MORE
