1. 11. Geometrical Improvement of Fuel Nozzle Locations in the SGT-750 Gas Turbine : An investigation into fuel-air mixing in main channels 1 & 2

   University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

   Author : Aryan Delir; [2022]
   Keywords : gas turbine engines; turbofan; combustion; SGT-750; flashback; hydrogen; natural gas; premixing; fuel-air mixing; computational fluid dynamics; CFD; turbulence modelling; NOx emission; lean premixed mixture;

   Abstract : This study was conducted on SGT-750, which utilizes can type fourth generation DLE burner, developed at Siemens Energy AB, in Finspång, Sweden. The aim of this study is to obtain a flat fuel profile at the outlet of main channel 1 and main channel 2, demonstrating a proper mixing of fuel and air in the main channels leading to reducing local high-temperature points, and thus, reducing thermal NOx emissions.

3. 12. LES modelling of spray combustion

   University essay from Lunds universitet/Institutionen för energivetenskaper

   Author : Arvid Åkerblom; [2021]
   Keywords : Gas Turbine; CFD; Large Eddy Simulation; Lagrangian Particle Tracking; Chemical Kinetics; Reaction Mechanism; Combustion; OpenFOAM; CHEMKIN; Technology and Engineering;

   Abstract : Computational fluid dynamics is a powerful method for understanding the flow and combustion that occurs inside aircraft engines and will be a key tool in the transition from conventional fossil-based fuel to sustainable alternatives. Because conventional fuels have been more widely researched, an attempt at simulating the combustion of alternative fuels should be preceded by the development of a method that is capable of accurately simulating the combustion of a conventional fuel.

4. 13. Design of flow guiding parts through CFD topology optimisation

   University essay from KTH/Fordonsdynamik

   Author : Aby Narayamparambil; [2021]
   Keywords : Topology optimisation in CFD; Ansys Fluent; Tosca Fluid; Particle track; Backflow tolerance; Topologi optimering i CFD; Ansys Fluent; Tosca Fluid; Particle track; Återflödets tolerans;

   Abstract : Scania works continuously to develop internal combustion engines and after treatment systems which can achieve low pollutant emissions and high efficiency. A major principal that Scania adopted for this goal is the Simulation Driven Development (SDD) process. READ MORE

5. 14. There is a New Road in Town

   University essay from Lunds universitet/Produktionsekonomi

   Author : Anton Lindström; Oscar Jakobsson; [2021]
   Keywords : Iterative research; Electric Road Systems; ERS; Electrification; Commercialization; Stakeholder analysis; Case study; Investment Decision; Investment modelling; Business and Economics;

   Abstract : This master thesis explores commercialization of electric road systems in urban environments, using a combined methods approach, in contrast to previous studies that have focused on long haul transportation. First, through interviews and document gathering, a stakeholder map was constructed, and the incentives of the identified stakeholders were analyzed. READ MORE

6. 15. Modelling and improvement of 2-Speed Smoothing System

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Oskar Nilsson; [2021]
   Keywords : Simulink; Skid-steer; Hydraulics;

   Abstract : A skid steer loader is a machine used in construction for multiple tasks. Its small size and versatility makesit a use-full addition to any work site. The machine is driven by a combustion engine that in turn powers ahydraulic pump. This hydraulic fluid from the pump is then directed to either motor to propel the vehicle. READ MORE
