Breakup dynamics of Newtonian fluids under extension [dataset]

Supporting data for "Breakup dynamics of Newtonian fluids under extension" by Allgood and Jones (2026) in Royal Society Open Science. ThinningVideoFiles.zip contains footage of all fluid extension experiments in .mp4 format, at 60 fps. The original videos were recorded at 1000 fps, but have been condensed here to reduce file sizes. The names of video files correspond to the details listed in Table A1 in the supplementary materials of the main text. ThinningData.txt contains raw data for fluid filament mid-plane diameter, measured via brightness thresholding in every frame of the original high-speed video footage. The names of experiments correspond to the video files, and to the details listed in Table A1 in the supplementary materials of the main text. Columns display experiment name (Name), time before breakup in seconds (Time_s), mid-plane diameter in pixels (D_px) and mid-plane diameter in millimetres (D_mm).本数据集为Allgood与Jones于2026年发表于《英国皇家学会开放科学（Royal Society Open Science）》的论文《拉伸条件下牛顿流体的断裂动力学（Breakup dynamics of Newtonian fluids under extension）》的配套支撑数据。 ThinningVideoFiles.zip 包含所有流体拉伸实验的.mp4格式录像，帧率为60 fps（帧每秒）。原始录像的录制帧率为1000 fps（帧每秒），本次发布已对其进行压缩以减小文件体积。视频文件名与正文补充材料中表A1所列的实验细节一一对应。 ThinningData.txt 包含流体细丝中平面直径的原始测量数据，该数据通过对原始高速录像的每一帧进行亮度阈值法处理得到。实验名称与视频文件名、以及正文补充材料表A1中列出的实验细节一一对应。数据列依次为：实验名称（Name）、断裂前时间（单位：秒，Time_s）、中平面直径（像素单位，D_px）以及中平面直径（毫米单位，D_mm）。
