循环流化床床内流场颗粒含量图像分析

Image analysis of particle concentration in circulating fluidized bed

借助二次开发的图像识别软件,对用PIV中CCD相机拍摄到的循环流化床(CFB)床内颗粒运动流场图像进行了图像处理,获得了床内截面上的颗粒含量分布图,结果分析反映了循环流化床床内颗粒含量及大小分布的一些特性。

The particle concentration and size distribution in circulating fluidized bed section is obtained through processing the image of flow field in CFB photographed by the CCD of PIV with the aid of software of image distinguishing. The analysis of result basically reflects the character of particle concentration and size distribution.
