Identification of structures driving trailing-edge noise. Part I -- Experimental investigation

Autor: Demange, Simon, Yuan, Zhenyang, Jekosch, Simon, Sarradj, Ennes, Hanifi, Ardeshir, Cavalieri, André V. G., Oberleithner, Kilian

Trailing-edge (TE) noise is the main contributor to the acoustic signature of flows over airfoils. It originates from the interaction of turbulent structures in the airfoil boundary layer with the TE. This study experimentally identifies the flow str

Methods for analyzing and characterizing sound sources in rotating systems

Autor: Jekosch, Simon

Sound generation by rotating machinery is oftentimes perceived as noise. Microphone array methods that rely on rotating beamforming are a versatile method to identify and locate these noise sources with high accuracy. To accurately analyze acoustic s

The characterization of rotating aeroacoustic sources using microphone array methods has been proven to be a useful tool. One technique to identify rotating sources is the virtual rotating array method. The method interpolates the pressure time data
