Frequency-domain data in 1/12th octave bands for aeroacoustic wind tunnel test of NACA63018 airfoil.

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. It is intended to be used in benchmarking exercises for open source software.The files consist of microphone array measurements. Here frequency-domain data (in 1/12th octave bands) is provided in HDF5 fileformat using the AIAA Array Methods HDF5 File Definition. Each file consist of raw data and associated metadata that includes geometry setup, flow and ambient conditions. This is documented in the ”AIAA Array Methods HDF5 File Definition” document.The measurement setup is described in the attached pdf-file NACA63018_acoustic.pdf

本数据集由在航空声学风洞（Poul la Cour 风洞，PLCT（https://www.plct.dk））内进行的声学测量构成，该风洞侧壁采用凯夫拉材料，并利用麦克风阵列进行测量。数据集旨在为开源软件的基准测试提供参考。文件包含麦克风阵列的测量数据。其中，频域数据（以1/12倍频程为单位）以HDF5文件格式提供，遵循AIAA阵列方法HDF5文件定义。每个文件均包含原始数据和相关的元数据，包括几何设置、流动条件和环境条件。相关信息详见于《AIAA阵列方法HDF5文件定义》文档。测量配置的详细信息可在所附的PDF文件NACA63018_acoustic.pdf中找到。
