A semi-empirical model which describes the influence of observed voidage variations on gas and particle flows associated with a fluidization bubble is described. It is shown that the effects are very slight so that the incompressible assumption used in Davidson's (1961) model is justified.

The aim of this study was to develop a practically usable model to describe the influence of mcreased gas density on the gas holdup m bubble column reactors. In order to develop an insIght into this effect, we performed extensive sets of experiments at pressures ranging from 0.1 MPa to 2 MPa and wit
