Medium-Frequency Acoustic Attenuation and Natural Convection in Nanofluids: Effect of Aggregate Size (ONESTEP)

This dataset contains acoustic information generated for the ONESTEP MSCA project relating to the attenuation of medium-frequency acoustic signals in carbon nanofluids. In ONESTEP (May 2023 to October 2025), we were interested in understanding the physics of photothermal boiling (boiling with light) through non-invasive acoustic techniques. However, early results indicated that higher frequencies were attenuated substantially, leading to further investigation and this dataset. The specific contents of this dataset are all relevant acoustic data (namely, amplitudes and frequencies) and data not used in the publication that were generated in the AEwin software (e.g., rise time, RMS, etc.). It is a stand-alone dataset and contains all relevant data to re-produce the associated publication or be reused for other research interests. Note that both the .DTA (AEwin software) and .CSV (plain text) file formats are available. See the Read Me file for further information.本数据集包含为ONESTEP MSCA项目生成的声学相关数据，该项目旨在研究碳纳米流体中的中频声学信号衰减现象。ONESTEP项目的实施周期为2023年5月至2025年10月，研究最初计划通过非侵入式声学技术解析光热沸腾（photothermal boiling，即光引发的沸腾过程）的物理机制。但初期实验结果显示，高频声学信号出现显著衰减，这一发现推动了后续研究，并催生了本数据集。本数据集的具体内容包含两类相关声学数据：其一为核心的振幅与频率数据；其二为通过AEwin软件生成、但未纳入已发表论文的辅助数据（如上升时间、均方根值（Root Mean Square，简称RMS）等）。本数据集为独立完整的数据集，涵盖可复现关联论文研究的全部相关数据，亦可复用于其他科研场景。请注意，本数据集提供.DTA（适配AEwin软件）与.CSV（纯文本）两种文件格式，详细信息请参阅Read Me文档。
