The CFD cross-sections from the simulations were extracted from two positions. The CFD data needed for the comparison to the experiment were taken at the outer wall of the model to match the perspective of the video.

The second position used in the CFD comparison of a rectangular versus a cylindrical tank were at the center of the impeller where the dynamics were most clear. The zero point was at the center of the 3D models, where X=0, Y=0 and Z=0.

The figure names contain the location at which the cross-sections was taken from, the relevant model, i.e. turbulent dissipation rate, turbulent kinetic energy, velocity magnitude, velocity vectors, solids suspension in terms of volume fraction (VF), 3D volume fraction renderings and the rotational velocity in terms of revolutions per minute (RPM).

The superimposed data figures names contain the VF that indicates the CFD function volume fraction, the rotational velocity (RPM), the time interval in seconds and SI to show the data was superimposed
