“…This is also in agreement with observations made in the literature (Smith et al, 1986;Matsumoto et al, 1991Matsumoto et al, , 1992 at similar location in the column. The procedure could be extended to systems of unknown particle size using multi-frequency measurements and appropriate calibration curves.…”

“…Notwithstanding minor variations in the definition of Up,, this still continues to be the most widely used approach to describe the mixing and segregation behavior of liquid or gasliquid fluidization of binary-or multisize mixture of solid particles (Juma and Richardson, 1983;Matsumoto et al, 1991). For example, Al-Dobbin and Garside (1979), like Kennedy and Bretton (1966), used the correlation of Richardson and Zaki (1954) to define the voidage function, f(e), for the evaluation of Up8 using Eq.…”

The mixing and segregation behavior of liquid fluidized beds containing two different-sized particle species are described mathematically. This model is based on a mass balance, rather than a volume balance, which has been used by most previous researchers. The model also includes the effects of density gradients that are present in the bed. Particle dispersion coefficients in a binary-solid fluidized bed are evaluated using this model. Further, a correlation that allows the calculation of these particle dispersion coefficients is presented, which describes not only dispersion coefficients calculated using the above model, but also those presented by other researchers. It is applicable over a broad range of variables of practical interest and is based on relevant dimensionless parameters to account for the influence of important particle and fluid properties on the particle dispersion characteristics.

“…Recently, Matsumoto et al (1991) investigated the axial changes in solid holdup for two-component systems of 118 and 243 µ , 118 and 465 µ , and 243 and 465 µ . Pa-rameters used in their model were correlated by empirical equations as functions of gas and liquid velocities, column diameter, and the properties of liquids and solids.…”
