PLCT-data: NACA63018 aeroacoustic - microphone array

Posted on 2024-05-14 - 09:31 authored by Oliver Ackermann Lylloff

This dataset consists of acoustic measurements conducted in an aeroacoustic wind tunnel (Poul la
Cour Tunnel, PLCT (https://www.plct.dk)) with Kevlar side walls using a microphone array.


The measurement setup is described in the pdf-document NACA63018-acoustic.pdf, and the data is provided in HDF5 fileformat using the AIAA Array Methods HDF5 File Definition (see document ArrayMethodsFileFormatsR2P4Release.pdf).


Both timeseries and frequency-domain data is available, and the filename convention is:
DTU_PLCT_NACA63018_[SURFACE]_[ADDON]_U0_[FLOWSPEED]_AoA_[AOA]_[SPECTRUMTYPE]_[CsmEss/TimeSeries].h5


The files are collected in items of either Timeseries, PSD (power spectral density) or octave-12 (1/12th octave bands), which is data from the same measurement but a different stages of post-processing.
