Abstract

Particle velocity, acceleration length and velocity profile evaluations are essential for the design and modeling in conveying systems. Although the subject was widely researched, the relationship between pneumatic and hydraulic systems has not been addressed and still lacks a correlation that will be consistent over various operating conditions and materials that concludes both conveying medias. The current paper presents a thorough experimental investigation of the above-mentioned characteristics obtained from 2-in dilute phase pneumatic conveying system and a 2-in hydraulic conveying system. Experiments with various operating conditions and conveyed materials in vertical orientations were conducted. The particle’s velocities and locations in the pipe were obtained using a high-speed camera combined with image processing. Data was obtained for each particle allowing an investigation of the effect each component has on the phenomena. Correlations are suggested for the characteristic’s evaluation in the range of the tested operating conditions.
