Aeroacoustic source characterization at fan test facility with spherical harmonics of the half-space
Year: 2025
Type: article
Abstract: Measured data for application of spherical harmonics of the half-space. In total the .zip file comprises 15 individual .h5 files of the measured data. One (1) file which includes the sampling frequency of all acoustic pressure signals: Sampling_frequecy_in_Hz.h5 (sampling frequency of acoustic signals) Eight (8) files correspond to measurements with a volume flow source: Measured at a Fan Performance Facility (FPF): VolumeSource_FPF_azimuth_in_rads.h5 (azimuth ordinates in rads of 65 microphone positions at FPF) VolumeSource_FPF_elevation_in_rads.h5 (elevation ordinates in rads of 65 microphone positions at FPF) VolumeSource_FPF_MicPressure_DefaultRoom_in_Pascal (acoustic pressure signals in Pascal at 65 microphone positions of default FPF) VolumeSource_FPF_MicPressure_AbsWall_in_Pascal (acoustic pressure signals in Pascal at 65 microphone positions of FPF with extra absorption on back wall). VolumeSource_FPF_MicPressure_AbsFloor_in_Pascal (acoustic pressure signals in Pascal at 65 microphone positions of FPF with extra absorption on the floor). Measured at a semi-anechoic (Semi): VolumeSource_Semi_azimuth_in_rads.h5 (azimuth ordinates in rads of 19 microphone positions at Semi) VolumeSource_Semi_elevation_in_rads.h5 (elevation ordinates in rads of 19 microphone positions at Semi) VolumeSource_Semi_MicPressure_in_Pascal.h5 (acoustic pressure signals in Pascal at 19 microphone positions of Semi) Six(6) files correspond to measurements with a low-pressyre axial fan at FPF: Fan_FPF_MicLocation_azimuth_in_rads.h5 (azimuth ordinates in rads of 65 microphone positions) Fan_FPF_MicLocation_elevation_in_rads.h5 (elevation ordinates in rads of 65 microphone positions) Fan_FPF_MicPressure_DesignPoint_in_Pascal.h5 (acoustic pressure signals in Pascal at 65 microphone positions for design conditions) Fan_FPF_MicPressure_OffDesign_in_Pascal.h5 (acoustic pressure signals in Pascal at 65 microphone positions for high loading) Fan_FPF_MicPressure_FreeDischarge_in_Pascal.h5 (acoustic pressure signals in Pascal at 65 microphone positions for low loading) NoFan_FPF_MicPressure_OnlyAxle_in_Pascal.h5 (acoustic pressure signals in Pascal at 65 microphone positions for only axle rotation,without fan)
