Miscible viscous fingering in a quarter-spot Hele-Shaw cell: Experimental dataset

This is the experimental dataset associated with the paper 'The effect of viscosity ratio and Peclet number on miscible viscous fingering in a Hele-Shaw cell: A combined numerical and experimental study' by Keable et al. 2021 - preprint available at https://arxiv.org/abs/2111.06548. This repository includes image and volumetric data described in the main paper. The images are used in the processing code available at https://github.com/sci-sjj/MiscibleViscousFingering. Images are included for M2, M5, M10 and M20 mobility ratios, performed at flowrate Q = 1ml/min. For M=20, we also include Q=0.1ml/min (filename M20_0_1mlpm), Q=0.5ml/min (filename M20_0_5mlpm), Q=5ml/min (filename M20_5mlpm) and Q=10ml/min (filename M20_10mlpm). Multiple repeat experiments are given filename extension v2, v3 etc (some experiments did not work so there may be missing v1 etc, extensions). The experiments at each flow rate and mobility ratio then have the following zipped folders containing images: _exp_images_time_lapse_raw.zip. These are the raw image files. _exp_images_time_lapse_processed.zip. These are cropped images from 1. _exp_images_time_lapse_final.zip. These are geometric transforms of 2, to be centered and aligned. They represent the final processed images. _exp_images_selected_PV.zip. These are selected images from 3 at different pore-volumes injection and times as a fraction of the breakthrough time. _exp_images_time_lapse_segmented.zip. These are segmented images used in interfacial calculations. Each image file in the above zipped folders follows the same prefix naming convention (e.g. M2_V2) followed by a number, e.g. (1000). Time sequences start at number 1000. Image capture times can be found in the image properties of the raw details to give aquisition rates. Full experimental details are listed in the paper, and also in the excel summary files on the github repository above. <br> <br> We include simulation image results, txt based macroscopic experimental results and literature results in zipped folders. These can be run using the github processing codes to produce the figures/analysis in the main paper.本数据集为Keable等人2021年发布的预印本论文《佩克莱特数（Peclet number）与粘度比对赫勒-肖槽（Hele-Shaw cell）内可混溶粘性指进现象的影响：数值与实验联合研究》的配套实验数据集，预印本可通过https://arxiv.org/abs/2111.06548获取。 本仓库包含主论文中描述的图像与体数据，配套的图像处理代码可在https://github.com/sci-sjj/MiscibleViscousFingering获取。 本数据集涵盖流度比（mobility ratio）为M2、M5、M10与M20的实验图像，所有工况均设置流量Q=1ml/min。针对流度比M=20的实验，额外提供了不同流量下的图像数据：Q=0.1ml/min（对应文件名为M20_0_1mlpm）、Q=0.5ml/min（对应文件名为M20_0_5mlpm）、Q=5ml/min（对应文件名为M20_5mlpm）与Q=10ml/min（对应文件名为M20_10mlpm）。 多组重复实验的文件名后缀为v2、v3等（部分实验失败，因此可能存在缺失v1等后缀的情况）。 针对每一组流量与流度比的实验，提供以下包含图像的压缩文件夹： 1. _exp_images_time_lapse_raw.zip：原始图像文件 2. _exp_images_time_lapse_processed.zip：对上述原始图像进行裁剪后得到的预处理图像 3. _exp_images_time_lapse_final.zip：对预处理图像进行几何变换后得到的居中对齐图像，即最终处理后的图像 4. _exp_images_selected_PV.zip：从最终处理后的图像中选取的、对应不同注入孔隙体积（pore-volume）与突破时间占比的图像 5. _exp_images_time_lapse_segmented.zip：用于界面计算的分割图像 上述压缩文件夹中的所有图像文件均遵循统一的前缀命名格式（例如M2_V2），其后跟随数字编号（如1000），时间序列从编号1000开始。原始图像的属性中包含拍摄时间信息，可用于获取采集速率。 完整的实验细节可查阅主论文，以及上述GitHub仓库中的Excel汇总文件。 本数据集还包含压缩文件夹形式的仿真图像结果、基于文本的宏观实验结果与文献结果，可通过GitHub上的处理代码运行以复现主论文中的图表与分析内容。
