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 monitoring
technique 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.
