| Abstract The dynamic high-speed CCD photographic measurement system has been developed, which covered the techniques of high-speed vision analysis system and computer disposal system of digital images. The behaviour of bubbles in annular regions of the two-phase three-dimension downward-jet loop reactor has been measured under various geometrical characteristics and working conditions. The results show that it is a rapid method to measure precisely the bubble parameters and can also be a standard of other bubble measurement methods in which probes are placed in the reactor. |
