离心流化床干燥器的流体力学及传热性能

Performances of Fluid Mechanics and Heat Transfer in Centrifugal Fluidized Bed Dryer

以9种颗粒物料为研究对象，找出了影响离心流态化干燥系统的流体力学及传热性能的主要因素，回归得到了流体力学及传热的无因次准数关联式。为进一步研究此设备的干燥性能打下了基础。

Experimental studies in a centrifugal fluidized bed dryer by using 9 kinds of particleswere performed. The main factors affecting.fluid mechanics and heat transfer were found. The corre-Iation formulas of the dimensionless groups for fluid mechanics and heat transfer were obtained. Thework is a basis for further studying the drying characteristics of the centrifugal fluidized bed dryer.
