Time-dependent behaviour of industrial granular materials under vibration: modelling and phenomenology.

This dataset contains all the videos from the snapshots in the article "Time-dependent behaviour of industrial granular materials under vibration: modelling and phenomenology" - Journal of Chemical Engineering Science. The publication deals with the densification kinetics of industrial granular materials using a particle damper. The densification/compaction is obtained by harmonic vibration with no time between excitations. All videos are named as the figure number from the publication. Also, two other videos were added to show some other phenomena observed. Online resource 1 shows the granulation of Sericite, a highly cohesive powder (mica) when vibrated at 11.5 g acceleration and 125 Hz frequency. The video is taken after 8 million excitations. Online resource 2 shows the fluidization during vibration for a slightly cohesive powder Avicel PH102 vibrated at 5.34 g acceleration and 30 Hz frequency. This video focus on the bubbling phenomena observed during the first seconds of vibration.本数据集收录了发表于《Journal of Chemical Engineering Science（化学工程科学期刊）》的论文《振动下工业颗粒材料的时变行为：建模与现象学》中所有快照对应的视频。该论文围绕采用颗粒阻尼器（particle damper）实现工业颗粒材料致密化动力学（densification kinetics）的研究展开，其致密/压实过程通过无激励间隔的简谐振动（harmonic vibration）完成。所有视频均以论文中的图号命名。此外，还补充了两段额外视频，用于展示其他观测到的实验现象。在线资源1展示了高黏性粉末Sericite（绢云母，即mica（云母））在加速度11.5g、振动频率125Hz条件下的造粒过程，该视频采集于800万次振动激励之后。在线资源2展示了轻微黏性粉末Avicel PH102在加速度5.34g、振动频率30Hz的振动过程中的流态化现象，该视频聚焦振动初始几秒内观测到的气泡现象。
