Vision-based particle velocity measurement in granular gas-solid flows with special focus on knowledge transfer

This paper describes the development of a gas-solid flow measurement setup based on an optical method to determine the particle velocity in granular material flow. Main aim of the setup is to provide students a substantiated practical knowledge in the fields of pneumatic conveying of bulk solids and the measurement of gaseous and particulate velocities in two-phase flows. The impact of sensor position on the measurement results is demonstrated in this paper.
