文摘

DIA measurements of a bubbling fluidized bed subjected to vibration were performed. Bubbles were individually tracked and their oscillations were analyzed. Amplitude and phase of bubbles oscillations depend on the distance to the distributor. Bubbles present a phase delay between the upper and lower sections of the bed.
