PREDICTION OF BUBBLE DYNAMICS IN A FLUIDIZED BED BY THE MEASUREMENT OF PRESSURE OSCILLATIONS
DOI: 10.1615/1-56700-127-0.170
pages 111-115
Sinopsis
In the present study, the pressure fluctuations in a two-dimensional transparent fluidized bed are measured by a pressure transducer such that the bubble formation and movement can be detected from the signals. Bubble movement is recorded by a video camera and signals obtained from the pressure transducer are stored in a computer. Bubble diameters and rise velocities are determined from pressure-time data utilizing image and signal processing techniques.
