摘要：
The mixings of particle in fluidized bed have an important effect on moving and combustion of particle. The mixing of CWP (Coal Water Paste) in the two-dimensional fluidized bed with jet is investigated by digital image processing. The characteristics of gas-solid jet are researched and the characteristics of gas-solid jet fluctuation are proved by means of Rescaled Range Analysis. The CWP congregates in the top of horizontal part of the jet and fluctuates with the jet. The CWP distorts, diffuses and mixes because of bubbles and jet fluctuation. The mixing of CWP is investigated by the correlation analysis of digital image. There are different mixing mechanisms in the different regions. The CWP mixes in the bottom region of jet-effect area by jet fluctuation and jet daggling, in the top and out region of jet-effect area by jet bubble moving and fluidized bubble moving. The gross circulation is strengthened because of presence of jet.
