  1. 1. A numerical comparison of the thermoacoustics for different equivalence ratios for n-dodecane using LES

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Björn Jarfors; [2023]
    Keywords : Computational Fluid Dynamics; Bluff-body stabilised flames; Large Eddy Simulation; Thermoacoustics; Acoustics; NEUMANN Project; Jet engines; Aero engines; Airplanes; Combustion; Numerics; Technology and Engineering;

    Abstract : Klimatförändringarna påverkar vår värld och det behövs ett mer hållbart samhälle. Flygindustrin är i behov av förändring, men flygmotorer är mycket komplexa och tar tid att utveckla. Termoakustiska instabiliteter har kraften att förstöra en motor, men också att minska miljöpåverkan. READ MORE

  3. 2. Compressor Surge: Simulation, Modeling and Analysis

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Robin Massiquet; [2022]
    Keywords : Turbo compressor; Surge; Simulation; Modelling;

    Abstract : The master thesis subject takes place in the automotive industry and specifically in the internal combustion engine area. The need of improving the efficiency of the engines leads to develop new technologies like turbo compressors. Some of the challenges to overcome are high rotational speed difficulties or extreme load and fatigue in the rotors. READ MORE

  4. 3. Detection and Identification of Instability and Blow-off/Flashback Precursors in Aeronautical Engines using Deep Learning techniques

    University essay from KTH/Kraft- och värmeteknologi

    Author : Antony Hermann Guy Cellier; [2020]
    Keywords : Thermo-Acoustic Instabilities; precursors; Deep Learning; Speech Recognition.;

    Abstract : The evolution of injection processes toward more fuel efficient and less polluting combustion systems tend to make them more prone to critical events such as Thermo-Acoustic Instabilities, Blow-Off and Flash-Back. Moreover, the addition of Di-Hydrogen as a secondary or as the main fuel is in discussion by aeronautical engines manufacturers. READ MORE

    Keywords : Industrial gas turbines; Combustion instabilities; Computational fluid dynamics; Acoustics; COMSOL Multiphysics; Flame transfer function;

    Abstract : Many industries have entered a new global phase which takes the environment in mind. The gas turbine industry is no exception, where the utilization of green fuels is the future to spare the environment from carbon dioxide and NOx emissions. READ MORE

  6. 5. CFD-Method for 3D Aerodynamic Adjoint Simulations : For External Automotive Aerodynamics

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Marcus Lång; [2019]
    Keywords : ;

    Abstract : Today’s rules and regulations regarding emissions from combustion vehicles are very strict and the travel range per tank and/or charge, especially for electric vehicles, is a crucial factor which will always be considered by the customers. Hence, automotive manufacturers strive to boost fuel and battery economy. READ MORE
