Design for urban vertical-axis wind turbines: balancing performance and noise

In urban areas, vertical-axis wind turbines (VAWTs) show promise due to their omnidirectional design, addressing challenges faced by traditional horizontal-axis turbines (HAWTs). Despite significant progress in urban VAWTs, extensive multidisciplinary research is needed to optimise their efficiency and use in such environments. <br/><br/>This...

Measurement techniques for aeroacoustics: From aerodynamic comparisons to aeroacoustic assimilations

Sustainability has encouraged studies focusing on lowering the aeroacoustic impact of new aerodynamically optimized mechanical systems for several applications in wind-energy, aviation, automotive and urban air-mobility. The deployment of effective noise-reduction strategies starts with a deep understanding of the underlying mechanisms of...

Acoustic Array Design: The design of a reconfigurable phased microphone array for aeroacoustic wind tunnel measurements

Since both the aircraft and wind energy sectors are experiencing rapid growth, improvements must be made in terms of noise reduction as to enable growth whilst fulfilling the restrictions on noise pollution. An open-section vertical wind tunnel with an anechoic test chamber has recently been constructed at the Delft University of Technology, in...
