Solids Fluxes In A Dilute Riser Measured By Pdpa

Based on phase Doppler particle analyzer (PDPA) measurement in a dilute gas-solid riser with a square cross-section, an algorithm was proposed to calculate local axial and lateral solids fluxes simultaneously. Lateral profile of axial solids flux is in good agreement with published data. Lateral solids flux is much lower than solids circulation rate despite approaching a maximum near the core-annulus boundary. The effect of operating conditions on lateral solids flux was also analyzed in this study.
