摘要
应用统计的方法对大量已有的离心通风机空气动力学略图和性能参数之间的内在关系进行分析研究 ,发现了比转数 ns与比直径数 Ds之间以及叶片出口宽度 b2 与比转数 ns 之间存在着的对应关系。
The internal relations between a large number of existing aerodynamic sketches & performance parameters of centrifugal fan are analyzed & investigated by statistical method.The correspondence relations between specific speed and specific diameter,specific speed and impeller outlet breadth are found.New method which determined the main geometric parameters of impeller is put forward.
