  1. 1. Oil Autonomy of a Turbojet

    University essay from KTH/Flygdynamik

    Author : Florian Steiner; [2022]
    Keywords : Fluid Mechanics; Turbojet; Oil circuit; Fluid Mekanik; Turbojet; Oljekrets;

    Abstract : The oil circuit of a jet engine is required to lubricate and cool mechanical parts. The oil is pumped from the oil tank and flows through heat exchangers. Then it is injected on the bearings for lubrication and cooling, before being scavenged at the bottom of the sumps and finally flows back to the oil tank. READ MORE

  3. 2. 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.

  5. 4. Hydraulic Characterization of Diesel Engine Single-Hole Injectors

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Javier Arco Sola; [2015]
    Keywords : ;

    Abstract : Due to world trend on the emission regulations and greater demand of fuel economy,the research on advanced diesel injector designs is a key factor for the next generation diesel engines. For that reason, it is well established that understanding the effects of the nozzle geometry on the spray development, fuel-air mixing, combustion and pollutants formation is of crucial importance to achieve these goals.
