A method of calculating particle velocities in gas-solid systems was developed using a cross-correlation technique. The particle velocity calculation was then used to test the validity of the theoretical gas-solid two-phase vertical flow diagram. Glass beads with a range of particle sizes from 150 to 200 ..mu..m were employed under solid-gas loadings to 10. Experiments were carried out in 0.0254 m dia. Plexiglas tube at low humidity (25%). The particle velocity could be measured within +-0.305 m/s using electrostatic ring probes with a probe separation of 0.61 m. No signal filtering was required. Comparison was made between the experimental results and the theoretical phase diagram.
