Abstract

The novel travelling fluidization column, designed and built to assure identical operating conditions, was deployed to compare alternate experimental measurement techniques for hydrodynamic characterization of gas-fluidized beds. This study compares measurements of particle velocity obtained by radioactive particle tracking (RPT – non-invasive at the Ecole Polytechnique), positron emissi on particle tracking (PEPT – non-invasive at University of Birmingham), optical fibre prob es (invasive at UBC) and borescopic high speed particle image velocimetry (invasive at PSRI) carried out with FCC and sand particles. Analysis ofthe time-average particle velocity profiles, focusing on the physical principles of each measurement technique provides valuable insights into the reasons of the discrepancy between the results.
