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. Design of Experiment Based on Full Factorial CFD Spray Modelling

   University essay from Lunds universitet/Institutionen för energivetenskaper

   Author : Olle Faritzon; [2023]
   Keywords : CFD; spray; liquid; injection; DoE; Design of Experiment; fuel spray; Propane; LPG; OpenFOAM; Experiment; Fluid dynamics; maritime shipping; engine; Technology and Engineering;

   Abstract : Design of experiment is a powerful tool that can reduce the amount of physical testing needed to save resources, time and money. A CFD-setup was constructed in OpenFOAM-8, simulating injection of liquid propane with a standard multi-hole injector. The model was then validated against experimental results. 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. Impacts of misbehavior in Intelligent Transportation Systems (ITS) : The case of cooperative maneuvers

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