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 in the hydrodynamics of multi-phase flow systems. 
The data was obtained using the single-photon emission radioactive particle tracking technique. 

The dataset consists of the following .fig and .opju files whereof a short description is given below:
