Studies on the onset velocity of turbulent fluidization for alpha-alumina particles

Transition from bubbling to turbulent fluidization regime for alpha-aluminaparticles was experimentally studied in the 0.15 m i.d. cold flow model. Experiments were carried out at 1 atm and ambient temperature. Both standard deviation and amplitude spectra analysis were used to determine the transition. Transition velocity of 0.8 m/s was obtained for the particles under investigation. (C) 2002 Elsevier Science B.V. All rights reserved.
