PARTICLE VELOCITY AND CONCENTRATION PROFILES DURING HYDRAULIC TRANSPORT IN A CIRCULAR PIPE

This paper reports measurements of particle velocities and concentrations in a circular pipe which are made by high speed cine photography of colored marker particles. The suspension is made clear by matching the refractive index of the remaining particles and the conveying liquid. The particle velocity and concentration profiles are determined for varying conveying velocities. The results are discussed in terms of the dynamic equilibrium conditions created by the competing mechanisms of particle mixing and gravitational settling.
