摘要
在试验研究的基础上，论述了周向涡流的基本特性和形成原因；指明涡流内部和边界上存在着两大不同的剪力层，它们将对风机系统效率产生较大影响。
On the basis of experimental research,the basic features and formal reasons of the circumferential vortex are discussed;two different shear force layers existed in the vortex interior and on the boundary are indicaled,the greater influence of the vortex on the fan system efficiency is presented.
