The development of the suspension of the silica particles inside the clear polycarbonate mixing tanks was captured on video. Software was used to extract data at one second intervals from the experimental videos. Autodesk AutoCAD was used to create 1:1 scale models of the captured images. The images were superimposed to accurately measure and compare the CFD imaged to the experimental cloud height.

The file names contain a RPM value that represents the rotational velocity of the impeller at which the experiments were performed. There were 6 repetitions performed at the rotational speeds of 600 and 750 rpm which is reflected in the additional number in the file name.
