This is a set of Matlab .fig and Origin .opju files corresponding to the figures in the paper 'Single-photon emission radioactive particle tracking method for hydrodynamic evaluation of multi-phase flows' published in Particuology. In this study, a single-photon emission radioactive particle tracking technique is introduced that can be employed to obtain insight into the hydrodynamics of multi-phase flow systems. The data was obtained using the single-photon emission radioactive particle tracking technique.
