4D X-ray micro-velocimetry data of multiphase flow perturbations in porous media

Raw and reconstructed time series data of X-ray tomographic microscopy (XTM) on drainage in a porous medium, with flow-tracing microparticles in the non-wetting phase (oil) while the latter displaces brine from the pores (dataset 073). Additionally, raw and reconstructed X-ray tomograms of the sample before the experiment are provided, in dry state (dataset 064) and brine-satured state (dataset 065). All reconstructed datasets are provided both with Paganin phase retrieval (in 8 bit format) and without (in 16 bit format).本数据集包含多孔介质排驱过程的X射线断层扫描显微镜（X-ray tomographic microscopy, XTM）时序原始与重建数据：实验过程中，非润湿相（油相）从孔隙中驱替盐水，且该油相内添加了流动示踪微颗粒，对应数据集073。此外，本数据集还提供了实验前样品的X射线断层扫描原始与重建图像，分别对应干燥状态（数据集064）与盐水饱和状态（数据集065）。所有重建数据集均提供两种处理版本：经帕金相位恢复（Paganin phase retrieval）的8位格式版本，以及未经帕金相位恢复的16位格式版本。
