Jyoti and Haese, 2019, "The transition from face dissolution to wormhole formation in a heterogeneous limestone based on the distribution of local dissolution rates"

The findings from the dataset presented here are described in the paper titled "The transition from face dissolution to wormhole formation in a heterogeneous limestone based on the distribution of local dissolution rates" by Apoorv Jyoti and Ralf. R. Haese from the Peter Cook Center for CCS Research at the University of Melbourne. A multicomponent reactive transport model at the pore-scale in combination with a flow-through experiment with intermittent high-resolution imaging of the pore network geometry is used to better understand the formation of dissolution patterns in porous limestone. The 3D images of the pore network were used for reactive-transport simulations to derive the distribution of local dissolution rates. The model was validated through the comparison of experimental and integrated calcite dissolution rates derived from simulations. The image-based change in pore geometry was limited to less than 3 mm from the inflow of acid due to the rapid acid neutralization from calcite dissolution. The dataset consists of three parts: 1) Raw image data from the micro-CT scanner, 2) Chemical analysis of the effluent presented in an excel file, 3) The three reactive transport models at T0, T2, and T4, consisting of the input files for COMSOL and PhreeqC.本数据集的相关研究成果已发表于墨尔本大学彼得·库克碳捕集与封存（CCS）研究中心的Apoorv Jyoti与Ralf R. Haese所撰写的题为《基于局部溶蚀速率分布的非均质石灰岩中从表面溶蚀到溶蚀虫洞（wormhole）形成》的论文中。 本研究采用孔隙尺度多组分反应输运模型，结合孔隙网络几何结构间歇式高分辨率成像的渗流实验，以深入阐明多孔石灰岩中溶蚀形态的形成机制。研究人员利用孔隙网络的三维图像开展反应输运模拟，进而推导局部溶蚀速率的分布特征。通过对比实验测得的方解石溶蚀速率与模拟所得的溶蚀速率，完成了模型的验证工作。由于方解石溶蚀可快速中和酸液，孔隙几何结构的图像变化被限制在距酸液入口不足3毫米的区域内。 本数据集包含三部分内容： 1. 微型计算机断层扫描（micro-CT）扫描仪采集的原始图像数据 2. 以Excel文件格式存储的流出液化学分析数据 3. T0、T2及T4三个时刻的反应输运模型，包含COMSOL与PhreeqC的输入文件
