Radial profiles of local gas and solid holdups and liquid interstitial velocities are measured in a large-diameter three-phase fluidized bed
and systematic studies are based on a comparison with data obtained in small-diame-ter fluidized beds. It is shown that radial profiles of gas holdup conform to the parabolic form equation. The distributions of solid particles holdup may be expressed by Eq. (7).Liquid velocities are well described by the modified circulating flow model.
