This is a set of Matlab .fig files corresponding to the figures in the paper 'Experimental gas-fluidized bed drying study on the segregation and mixing dynamics for binary and ternary solids' published in Chemical Engineering Journal.
In this study, experiments in a pseudo-2D fluidized bed setup were performed to obtain insight in the complex and changing bed hydrodynamics and its interplay with mass and heat transfer. 
The data was obtained by using a combined Particle Image Velocimetry (PIV), Digital Image Analysis (DIA) and Infrared (IR) technique. Furthermore, a machine learning algorithm was applied in order to determine the segregation and mixing dynamics.

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