In developing his powder classification, Geldart [D. Geldart, Powder Technol. 7 (1973) 285.] employed fluidization data obtained only at ambient temperature and pressure and from beds fluidized only with air. Unfortunately, industrial applications of fluidized bed technology invariably are at elevat
## AbstracbIn gas-fluidized beds bubbling starts when the voids formed by the oscillating bottom layer of the bed exceed a minimal size. The so-called vibration criterion derived predicts the porosity at the bubble point in close agreement with the experimental data. Comparison of the other criter
