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. Electric conversion of combustion engine cars

   M1-uppsats, KTH/Hållbar produktionsutveckling (ML)

   Författare :Annika Modling; Bobby Åbrandt; [2022]
   Nyckelord :Electric conversion; combustion engine; electric motor; lithium-ion; lead-acid; DIY; second hand; Elkonvertering; förbränningsmotor; elmotor; litiumjon; blysyra; DIY; begagnat; cirkulär process;

   Sammanfattning : The electrification of personal transport vehicles is one of the strategies to counteract global warming and dependance on fossil fuels. Diesel powered cars are already prohibited in several big cities and the prices for fuel are constantly climbing. LÄS MER

4. 3. Enhancement of evaluation method of journal bearings’ performance in heavy-duty diesel engines

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

   Författare :Sateesh Nataraj; [2021]
   Nyckelord :Asperity contact pressure; elastohydrodynamic lubrication; friction; flow factors; run-in wear profile; Asperitetskontakttryck; elastohydrodynamik; friktion; flödesfaktorer; slitageprofil efter inkörning;

   Sammanfattning : Journal bearings are being used in various locations of an internal combustion engine. They contribute to a large portion of total engine friction and lowering it means a significant contribution to CO2 reduction. LÄS MER

5. 4. Evaluation of transition towards zero emission commuter ferries : Comparative Analysis of Fuel-based and Battery-based Marine Propulsion System from financial and environmental perspectives

   Master-uppsats, KTH/Marina system

   Författare :Varun Goel; Sonja Wadelius; [2021]
   Nyckelord :Water-borne public transport; Maritime industry; marine propulsion system; marine Li-ion batteries; diesel-electric; diesel-mechanical; all-electric; life cycle assessment; cost assessment.; Vattenburenkollektivtrafik; marinaindustrin; marinaframdrivningssystem; marinabatterisystem; dieselelektrisk; diesel mekanisk; helt elektrisk; livscykelanalys; kostnadsanalys.;

   Sammanfattning : The purpose of this study is to compare the life-cycle cost and environmental impact of the existing fuel-based propulsion system, on public commuter ferries in Stockholm, with a battery based propulsion system. The study is divided into multiple layers. LÄS MER

7. 5. Calibration and Validation of Efficient Combustion and EmissionModels for 3D-CFD EngineSimulations

   Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

   Författare :Vikas Shettihalli Anandreddy; [2019]
   Nyckelord :;

   Sammanfattning : To accurately analyze combustion and emissions in the internal combustion engine, hundreds of chemical species have to be transported in the computational domain in the form of a detailed chemical mechanism. The use of this detailed chemical mechanism in the computational domain leads to an increase in computational time. LÄS MER
