The noise radiation from unmanned aerial vehicles is measured in both anechoic chamber and outdoor environments. The effects of microphone arrangement, data processing method, requirements on whether condition, flight a…
View researchAerodynamic and aeroacoustic characteristics of a cylinder with longitudinal grooves were studied in an anechoic wind tunnel, emphasizing on drag and noise attenuation. The parallel mounted load cells and a single micro…
View researchThe aerodynamic noise generated by a two-dimensional large obstacle in a turbulent boundary layer. The obstacles have different shape and height emerged in the turbulent boundary layer of the flat plate. The spectra of …
View researchIn aeroacoustics, the far-field directivity is often computed using the integral solution of the acoustic analogy equations. The sound prediction can be rendered when the turbulent eddies move across the integration…
View researchAn experimental and computational investigation was carried out to determine the aerodynamics and aeroacoustics of a flap side-edge.
View researchAcoustic liners application within the nacelle walls is a well established passive noise damping technique in modern turbofan engine. Improved acoustic liners should be developed to improve the maximum noise attenuation…
