  1. 11. 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. 12. Measurement and Evaluation of Scattering Coefficient for Diffusing Panel

    University essay from KTH/Teknisk akustik

    Author : Frida Ekner; [2023]
    Keywords : Mechanics; acoustics; scattering; Mekanik; akustik; spridning;

    Abstract : In this work the aim was to determine the scattering coefficient for a diffusing panel by measurements and also examine the difference between scattering and diffusion. Similar measurements have been carried out in the past in slightly different ways, the method that was chosen was to follow a given standard for the measurement of the scattering coefficient.

  4. 13. Model-based synthesis of singing

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Xiaofeng Zeng; [2023]
    Keywords : Singing voice synthesis; Source-filter model; Anti-resonances; SuperCollider; Sång röstsyntes; Käll-filtersmodell; Anti-resonanser; SuperCollider;

    Abstract : The legacy KTH Music and Singing Synthesis Equipment (MUSSE) system, developed decades ago, is no longer compatible with contemporary computer systems. Nonetheless, the fundamental synthesis model at its core, known as the source-filter model, continues to be a valuable technology in the research field of voice synthesis. READ MORE

  5. 14. Development of a Low Noise Drone Propeller Using CFD Simulations

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Axel Schulz; [2023]
    Keywords : Drone Propeller Low Noise Computational Fluid Dynamics CFD; Technology and Engineering;

    Abstract : Noise pollution generated by drones has in recent years become a concern for humans and wildlife and has in some regions resulted in regulatory backlash. This thesis investigates the possibilities of developing a low noise drone propeller using computational fluid dynamics (CFD) simulations. READ MORE

  6. 15. Stable diffusion for HRIR extrapolation : A novel approach with deep learning

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Axel Rooth; [2023]
    Keywords : Head-related filter; Generative AI; Diffusion; Huvud-relaterat filter; Generative AI; Diffusion;

    Abstract : Humans perceive and interact with their environment through a multitude of sensory channels. Among these, hearing plays a pivotal role, enabling humans to effectively navigate their surroundings. READ MORE
