Bubble characteristics such as bubble size and rising velocity in three-phase fluidized beds provide the basic information for analyzing phase holdup, axial and radial mixing and heat and mass transfer characteristics. The relationship between the bubble size and its rising velocity and the bubble size distribution in three-phase fluidized beds have been investigated. On the other hand, bubble size reduction has been observed by addition of floating bubble breakers. This paper presents a study on the bubble holdup mean velocity, and mean bubble chord length in a three-phase fluidized bed of 0.254 m-ID with four different particle sizes (0.4--6.0 mm).
