摘要
论述了离心通风机叶轮进口相对涡流的产生及其变化规律。分析了相对涡流与流体预旋及叶轮内流的内在联系。初步探讨了影响相对涡流变化规律的重要因素。
Produce & Change low of relative vortex at impeller inlet of centrifugal fan are discussed.Internal relations of relative vortex,fluid pre-revolving & impeller internal folw are analyzed.The mian factors which affect the change low of relative vortex are initially inquired into.
