Frequency-domain data in PSD 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 PSD (Pa^2/Hz) 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

本数据集包含在气动声学风洞（Poul la Cour 风洞，PLCT（https://www.plct.dk））中进行，采用凯夫拉侧壁并使用麦克风阵列进行的声学测量。该数据集旨在用于开源软件的基准测试。数据文件包含麦克风阵列的测量结果。其中，频域数据以功率谱密度（Pa²/Hz）的形式提供，并采用 HDF5 文件格式，遵循 AIAA 麦克风阵列 HDF5 文件定义。每个文件均包含原始数据和相关的元数据，这些元数据包括几何设置、流动条件和环境条件。具体内容详见“AIAA 麦克风阵列 HDF5 文件定义”文档。测量设置详述于附件中的 pdf 文件 NACA63018_acoustic.pdf。
