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题为《基于局部溶蚀速率分布的非均质灰岩中表面溶蚀向虫洞形成的转变》的论文，作者为墨尔本大学彼得·库克碳捕获与封存（CCS）研究中心的Apoorv Jyoti与Ralf R. Haese。本研究采用孔隙尺度多组分反应输运模型，结合带间歇式高分辨率孔隙网络几何成像的渗流实验，以深入解析多孔灰岩中溶蚀形态的形成机制。研究借助孔隙网络的三维图像开展反应输运模拟，以此推导局部溶蚀速率的分布特征。通过对比实验与模拟所得的累计方解石溶蚀速率，对该模型进行了验证。由于灰岩中方解石溶蚀会快速中和酸液，基于成像观测到的孔隙几何结构变化被限定在距酸液入口不足3毫米的区域内。本数据集共包含三部分内容：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）Excel文件中存储的流出液化学分析结果；3）T0、T2及T4时刻的三套反应输运模型，包含COMSOL与PhreeqC的输入文件。
