| Abstract: | A concept of jet-influenced area is presented. The probability of the presence of jet in the jet-influenced area and the range of the jet-influenced area are studied by means of image processing and statistical method. The effects of the fluidization numbers, jet velocity and particle diameter on the jet-influenced area are investigated. With the increase in fluidization numbers, jet velocity and particle diameter, the jet-influenced area expands. |

| Keywords: | fluidized bed jet fluctuation jet-influenced area |
