1. Numerical Study on Acoustic Phenomena in Cavities for Aero-engine Applications
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : For about seventy years, noise generated by grazing flow past a cavity has been thoroughly studied. Yet, a coherent theory that describes such phenomena is missing. Lately, this phenomena started to be investigated in bleeding systems of aero-engines. LÄS MER
2. Room Impulse Response Interpolation
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : In Virtual Reality (VR) systems, the incorporation of acoustics allows for the generation of audio-visual stimuli, facilitating applications in engineering, architecture, and design. The goal of virtual acoustics is to create a realistic sound field in continuous space. LÄS MER
3. Simulation of low frequency acoustic waves in small rooms : An SBP-SAT approach to solving the time dependent acoustic wave equation in three dimensions
Kandidat-uppsats,Sammanfattning : Low frequency acoustic room behaviour can be approximated using numerical methods. Traditionally, music studio control rooms are built with complex geometries, making their eigenmodes difficult to predict mathematically. LÄS MER
4. A numerical comparison of the thermoacoustics for different equivalence ratios for n-dodecane using LES
Master-uppsats, Lunds universitet/Institutionen för energivetenskaperSammanfattning : 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. LÄS MER
5. Development of a Low Noise Drone Propeller Using CFD Simulations
Master-uppsats, Lunds universitet/Institutionen för energivetenskaperSammanfattning : 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. LÄS MER
