## Measurements of the visible bubble flow rate and the through-flow velocity of gas inside bubbles were made in a pressurized fluid&d bed, using capacitance and Pitot-static pressure probes, respectively. The influence of pressure and fluidiition velocity on the bubble behaviour and gas Row distr
The hydrodynamics have been studied in a cold, freely bubbling, pressurized fluidized bed. The bed has a cross-section of 0.2 m;0.3 m and was operated at pressures between 0.1 and 1.6 MPa and at excess gas velocities of 0.2 and 0.6 m/s. The bed material was silica sand with a mean particle diameter
## 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
