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

本数据集收录了于空气声学风洞（波尔·拉库尔风洞，Poul la Cour Tunnel, PLCT，https://www.plct.dk）中开展的声学测量数据，该风洞采用凯夫拉（Kevlar）侧壁结构，实验过程使用了麦克风阵列（microphone array）。本数据集旨在用于开源软件的基准测试工作。所有文件均为麦克风阵列测量数据，其中频域数据以1/12倍频程频段形式存储，采用AIAA阵列方法HDF5文件定义（AIAA Array Methods HDF5 File Definition）规范保存为HDF5格式文件。每份文件均包含原始测量数据与配套元数据，元数据涵盖实验几何设置、流场与环境条件等信息，相关规范可查阅《AIAA Array Methods HDF5 File Definition》文档。本次测量的具体设置详见附带的PDF文件NACA63018_acoustic.pdf。
