循环流化床中贴壁回探流的机理试验研究

An Experimental Study of Wall adhered Return Flow Mechanism in a Circulating Fluidized Bed

通过在循环流化床模型上（高度５．９ｍ，内径０．１４ｍ）进行的试验研究，探讨了贴壁回探流的形成机理，提出了贴壁回探流的物理模型。对工程设计和循环床理论研究都有意义。

.Through an experimental study conducted on a circulating fluidized bed model (height 5.9 m,inner diameter 0.14 m)the formation mechanism of a wall adhered return flow was explored and discussed with a physical model of the wall adhered return flow proposed.The above work is meaningful for both engineering design and theoretical research of circulating fluidized beds.
