• Bubbling, jetting and spouting as gas discharge modes at a single nozzle in a two-dimensional gas-fluidized bed with Group B particles were investigated by means of visual observation and spectral analysis of pressure fluctuations in the grid region. A bubble plume was observed with a frequency of bubble formation in the range 2–7 Hz. Empirical equations predicting the transitions of gas discharge modes were obtained. The flow regimes of gas discharge modes were mapped by using two parameters, the static bed height-to-nozzle diameter ratio and a modified two-phase Froude number.
