| Abstract | The velocity of a dense down flow of particles in a conduit can be measured in-line and non-invasively using acoustic waves to detect the passage of characteristic patterns in the local voidage. These patterns are, however, distorted as they flow through the conduit due to the relative motion between the particles, and shear zones at the wall. This work investigates the effect that the particle velocity and acoustic sampling parameters have on the correlation and velocity measurement of these patterns. (C) 2000 Elsevier Science Ltd.
