Relevance of local dispersion on mixing enhancement in Engineering Injection and Extraction systems in porous media: Insights from laboratory bench-scale experiments and modeling

In this study, we performed laboratory bench-scale experiments mimicking an engineered injection extraction (EIE) system in an unconfined aquifer. We investigated flow dynamics, transport, mixing processes and the role of local dispersion in mixing enhancement. We performed five experiments: two base-case experiments for each grain size (Coarse-Base and Fine-Base) and three experiments under transient flow conditions (Coarse-A, Fine-A and Fine-B).
The dataset includes:
1. The animation of the images taken every 30 seconds for the experiment Coarse-A
2. The animation of the images taken every 30 seconds for the experiment Fine-A
3. The animation of the images taken every 30 seconds for the experiment Fine-B

在本研究中，我们于非限制性含水层中模拟了工程注入提取（EIE）系统的实验室台架试验。我们探讨了流体动力学、传输、混合过程以及局部扩散在混合增强中的作用。我们进行了五次实验：每种粒径（粗粒基和细粒基）各两个基准实验，以及在瞬态流动条件下的三个实验（粗粒-A、细粒-A和细粒-B）。数据集包括：1. 每30秒拍摄的实验Coarse-A图像的动画；2. 每30秒拍摄的实验Fine-A图像的动画；3. 每30秒拍摄的实验Fine-B图像的动画。
