Methodologies and algorithms for sound propagation in complex environments with application to urban air mobility: A ray acoustics approach

Aerodynamic Noise Reduction with Porous Materials: Aeroacoustics Investigations and Applications

Public annoyances due to noise emission in aviation and wind energy sectors are expected to become more severe in the near future with increasing number of civilian flights and wind turbine installations. Such trend demands for deeper investigations into the noise generation mechanisms and the means to mitigate them. This dissertation addresses...

A study on the near-surface flow and acoustic emissions of trailing edge serrations: For the purpose of noise reduction of wind turbine blades

The flow near the surface, and the acoustic emissions of trailing edge serrations are investigated in this work. The use of this family of aerodynamic devices on airfoils is intended for the reduction of turbulent boundary layer-trailing edge noise (TBL-TE noise). This purpose has been well demonstrated in wind tunnel and numerical experiments....
