Abstract

An experimental study has been made of particle motion and the minimum gas velocity to transport particles in a vertical pipe. Particles with different properties (material, diameter and shape) were used in the experiment. A measuring system based on a video camera and image processing computer were used to record particle trajectories. Experimental results show that the particle-wall collision is the most influential factor for the particle motion even in the vertical pipe flow. it was also found that the particle concentration is closely related to particle shape and the coefficient of restitution.
