1. 1. 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. 2. 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. 3. Fundamental combustion properties of alternative fuels for energy transition

   University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

   Author : Yijing Mao; [2020]
   Keywords : Physics and Astronomy;

   Abstract : Validation and improvement of chemical kinetic modelling require accurate experimental data. The over goal of the present work is to obtain accurate data by using techniques that have been previously implemented in common flames, e.g. READ MORE

5. 4. Next generation expedition stove : A lead user approach to product development

   University essay from KTH/Maskinkonstruktion (Avd.)

   Author : Frida Rybo; Alfred Söder; [2020]
   Keywords : Outdoor equipment; lead user approach; Gioia methodology; expedition; stove; Friluftsutrustning; lead user; Gioia; expedition; friluftskök;

   Abstract : In 1996 Primus launched their expedition stove Multifuel, the first stove that could run on liquified petroleum gas (LPG), white gas, kerosene and aviation fuel. The multi-fuel stoves are part of the Primus expedition range of equipment. The line was designed and built to perform in extreme conditions. READ MORE

6. 5. A comparison of the multicomponent model and the mixture averaged approximation

   University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

   Author : Martin Torstensson; [2014]
   Keywords : Combustion physics; computational physics; multicomponent model; mixture averaged approximation; Physics and Astronomy;

   Abstract : In this work the major models for calculating diffusion in simulations of a laminar premixed hydrogen flame, the mixture averaged approximation and the multicomponent model, are explained and compared. This is done in order to see if the accuracy gained in implementing the multicomponent model is enough to warrant the increased workload the transition will cause. READ MORE
