Data underlying the publication: Experiments on floating bed rotating drums using magnetic particle tracking

Magnetic Particle Tracking (MPT) was employed to study a rotating drum filled with cork particles, using both air and water as interstitial medium. This non-invasive monitoringtechnique allows for the tracking of both particle translation and rotation in dry granular and liquid-solid systems. The data set spans two interstitial media, two filling degrees and four rotational velocities. These well-defined experiments and in-depth characterisation performed in this work provide an excellent validation case for multi-phase flow models.本研究采用磁颗粒追踪（Magnetic Particle Tracking, MPT）技术，对以空气、水分别作为间隙介质的填充软木颗粒旋转滚筒开展实验。该无创监测技术可实现干颗粒体系与液固体系中颗粒平动与转动的追踪。本数据集涵盖两种间隙介质、两种装填率以及四种旋转转速。本研究中开展的设计严谨的实验与深度表征工作，可为多相流模型提供优质的验证案例。
