摘　　要：利用图像处理技术在二维流化床试验装置上研究了水煤膏的混合过程。分析了垂直向上射流的脉动特性。利用数字图像相关性分析方法得到了水煤膏在流化床内的混合过程 ,指出水煤膏在流化床内混合的机理 。The mixing of CWP (Coal Water Paste)in the two dimensional fluidized bed with jet was investigated by digital image processing. The characteristics of gas solid jet are researches.The mixing of CWP was investigated by the correlation analysis of digital image. There are different mixing mechanisms in the different regions. The gross circulation is strengthened because of presence of jet.
