Results The semifluidization velocity, Gsf, rangesbetween the onset of semifluidization
velocity, Goa (, ie, the velocity at which the first particle touches the top restraint and the …

Data on liquid—solid semi-fluidization characteristics for heterogeneous mixtures are
reported. Values of the minimum semi-fluidization velocity obtained from experimental …

The necessity of a generalized correlation for predicting the maximum semi-fluilization
velocity is stressed. The experimental set up used for the study has been described in detail …

Data on semifluidization characteristics of a few gas-solid systems are reported and the
effects of different parameters discussed. Correlations for predicting the minimum and …

Experimental data on pressure drop in liquid—solid semifluidization have been interpreted
in terms of a newly defined friction factor (f), which has been successfully correlated as a …

Introduction Semifluidization is a new type of solid-fluid con-tacting technique, which has
been reported in the last decade only. It is claimed to be a compromise be-tween the packed …

This paper predicts heat transfer coefficient in semi-fluidized beds as a function of properties
of solid, gas and operating conditions. It includes collected data on heat transfer coefficient …

The semi-fluidization phenomenon can be viewed as the combination of a batch fluidized
bed at the bottom and a fixed bed at the top. Such a bed can be formed by providing …
