“…Even though these time-averaged parameters were generally taken to characterize multistage bubble columns, e.g. as in [9][10][11][12][13][14][15][16], only little is known about local and time-depending processes in multistage bubble columns. That dynamic processes might show an important impacts, signifies the fact that lateral low-frequency movement of the liquid phase on sieve trays of distillation plates have been found to cause stability problems in large columns [17][18][19].…”

Acoustic and visual study of bubble formation processes in bubble columns staged with fibrous catalytic layers

High-speed images of bubbly flow coupled with simultaneous passive acoustic measurements were carried out in a bubble column staged with structured fibrous catalysts. Local observations made with a high-speed camera system allow a detailed understanding of the influence of fabric structure on bubble formation processes and the determination of the Sauter bubble diameter. With acoustic measurements, the building frequency of bubble swarm formation is identified to be a linear function of the superficial gas velocity. Due to bubble size and building frequency of bubble swarm the percentage of simultaneously operative sites (holes at which bubbles were formed simultaneously) is calculated.
