In this paper,for the purpose of investigating the selection criterion of the hub-tip ratio when designing a counter-rotating axial flow fan using the constant circulation flow pattern method,five counter-rotating axial flow fans have been designed with different hub-tip ratio and numerical research has been carried out to study these fans.
为了研究采用等环量设计方法设计对旋轴流通风机时轮毂比的选择准则,以不同的轮毂比设计了5种对旋轴流通风机,并对这5种风机进行了数值研究。
