Abstract

An experimental study of gas-particle flow was conducted in the horizontal test section of a recirculating pipe flow loop. Glass beads with the size distribution up to 80 μm were transported with a bulk velocity of 12.6 m/s in a horizontal pipe with 127 mm inner diameter. Particle volume fractions varied from 5×10-5 to 4×10-3 to investigate the change in flow characteristics due to particle presence. The instantaneous local particle velocity and density were obtained by a time averaging method. A synchronized PDPA and LDV were used to expand measurement capability for dense flow. It was found that both axial and transverse mean and fluctuation velocities of gas and particle phases were affected by the variation of particle loading. Gravity showed great effect to particle concentration and particle size distribution in the horizontal pipe.
