Supplementary Data for our paper entitled "Aerodynamic levitation of nanofluid drops"

NOTE: A corrected version (rev1) of this dataset is published: https://doi.org/10.5281/zenodo.18896271 INSTRUCTION: Unzip Data.zip to view the dataset. Supplementary Data for our paper entitled "Aerodynamic levitation of nanofluid drops". Data is separated into three main folders with the following directory structure: Data||Camera1||||TimeData||||||[E3_RX_[FluidType]_[NeedleColor]_M_D_Y] x72|||||CharacteristicShapes_Cam1.csv||||Properties_Cam1.csv|||Camera2||||TimeData||||||[E3_RX_[FluidType]_[NeedleColor]_M_D_Y] x72|||||CharacteristicShapes_Cam2.csv||||Properties_Cam2.csv|||SpectraData||||SpectraData.csv|||Readme.txt Video IDs:The data of each video has an ID associated with it with format:E3_RX_[FluidType]_[NeedleColor]_M_D_Y E3 - all trials have this identifier. These were the third set of experiments preformed with the constructed wind tunnel. RX - the replicate number. There are three replicates for each fluid type and needle number with X = 1, 2, or 3. The numbering is arbitrary. There are three exceptions to the replicate numbering scheme:E3_R3_S1_Purple_7_11_2024E3_R4_S1_Purple_7_11_2024E3_R5_S1_Purple_7_11_2024where R3, R4, and R5 are the three replicates for the Purple needle with the S1 fluid type. There are no R1 or R2 since the videos were reshot to improve data reliability. [FluidType] - the fluid composition of the drop. There are eight types with the physical property of each discussed within the main body of the publication:DW - Distilled waterS1 - Distilled water with 0.02% Triton X-100N1 - Distilled water with 1% silicon dioxideN1S1 - Distilled water with 1% silicon dioxide and 0.02% Triton X-100N2 - Distilled water with 0.5% silicon dioxideN2S1 - Distilled water with 0.5% silicon dioxide and 0.02% Triton X-100N3 - Distilled water with 0.1% silicon dioxideN3S1 - Distilled water with 0.1% silicon dioxide and 0.02% Triton X-100 [NeedleColor] - The color of the needle from where the drop was released which corresponds different internal diameters discussed within the main body of the publication:Olive - 1.6 mmGreen - 1.19 mmPurple - 0.84 mm M_D_Y - the month, day, and year each trial video was shot. File contents:CharacteristicShapes_CamX.csv - where X = 1 or 2 for either camera. This table contains parameters of the characteristic shape. Additionally, time-average volume equivalent diameter and are equivalent diameter are included. Properties_CamX.csv - where X = 1 or 2 for either camera. This table contains frame rate information, number of total frames shot, and resolutions of the cameras. All camera 1 trials have the same resolution as do all camera 2 trials as discussed in the main body of the publication. SpectraData.csv - this table contains the normalized Axisymmetric, Horizontal, and Transverse amplitudes from the frequency spectra which correspond to the data in the publication. A value of "0" indicates that the given mode was not noted in the spectra. Extracted frequencies for each are also listed. Camera 1 data was used in most cases. In select trials, camera 2 data was used instead due to better recovery as compared to camera 1 counterpart. E3_RX_[FluidType]_[NeedleColor]_M_D_Y - These are tables which contain measurements for the binarized drop at each frame.注意：本数据集的修订版本（rev1）已正式发布，链接为：https://doi.org/10.5281/zenodo.18896271 操作说明：请解压Data.zip以查看本数据集。 本数据集为论文《纳米流体液滴的气动悬浮》的补充数据。 数据集分为三个核心文件夹，目录结构如下： Data ├─ Camera1 │ ├─ TimeData │ │ ├─ 共72个以[E3_RX_[流体类型]_[针管颜色]_月_日_年]命名的子文件夹 │ │ │ ├─ CharacteristicShapes_Cam1.csv │ │ │ └─ Properties_Cam1.csv ├─ Camera2 │ ├─ TimeData │ │ ├─ 共72个以[E3_RX_[流体类型]_[针管颜色]_月_日_年]命名的子文件夹 │ │ │ ├─ CharacteristicShapes_Cam2.csv │ │ │ └─ Properties_Cam2.csv ├─ SpectraData │ └─ SpectraData.csv └─ Readme.txt 视频ID说明：每个视频的数据均关联唯一ID，格式为E3_RX_[FluidType]_[NeedleColor]_M_D_Y。 - E3：所有试验均包含该标识符，代表本次实验为搭建的风洞开展的第三组试验。 - RX：重复试验编号。每种流体类型与针管组合均包含3组重复试验，X取值为1、2或3，编号为随机分配。但存在3组例外：E3_R3_S1_Purple_7_11_2024、E3_R4_S1_Purple_7_11_2024、E3_R5_S1_Purple_7_11_2024，即使用S1流体与紫色针管的试验组共3组重复试验，编号为R3、R4、R5，因原视频重拍以提升数据可靠性，故无R1、R2编号。 [FluidType]：液滴的流体组分，共8种类型，各组分的物理性质详见论文正文： - DW：蒸馏水 - S1：添加0.02% Triton X-100的蒸馏水 - N1：添加1%二氧化硅的蒸馏水 - N1S1：添加1%二氧化硅与0.02% Triton X-100的蒸馏水 - N2：添加0.5%二氧化硅的蒸馏水 - N2S1：添加0.5%二氧化硅与0.02% Triton X-100的蒸馏水 - N3：添加0.1%二氧化硅的蒸馏水 - N3S1：添加0.1%二氧化硅与0.02% Triton X-100的蒸馏水 [NeedleColor]：液滴释放所用针管的颜色，对应不同的内径尺寸，具体参数详见论文正文： - Olive（橄榄色）：1.6 mm - Green（绿色）：1.19 mm - Purple（紫色）：0.84 mm M_D_Y：每次试验视频拍摄的月、日、年。 文件内容说明： 1. CharacteristicShapes_CamX.csv（X=1或2，对应摄像头1或2）：该表格包含特征形状的相关参数，同时包含时间平均体积等效直径与面积等效直径。 2. Properties_CamX.csv（X=1或2，对应摄像头1或2）：该表格包含帧率、总拍摄帧数与摄像头分辨率信息。如论文正文所述，所有摄像头1的试验采用相同分辨率，所有摄像头2的试验亦采用相同分辨率。 3. SpectraData.csv：该表格包含归一化的轴对称、水平与横向振动模式的频谱幅值，与论文中的数据相对应。若幅值为"0"，则代表该振动模式未在频谱中被检测到。同时表格中列出了各模式的提取频率。多数试验采用摄像头1的数据，仅少数试验因摄像头2的数据恢复效果优于摄像头1，故改用摄像头2的数据。 4. E3_RX_[FluidType]_[NeedleColor]_M_D_Y：该类表格包含每一帧中二值化液滴的测量数据。
