摘　　要：在基于势流理论的螺旋桨升力面理论设计中,一般忽略桨毂的作用,限制叶根环量为零,在处理边值问题时仅考虑桨叶而忽略桨毂。本文将二维流动问题中的镜像法与升力面方法相结合,建立考虑桨毂作用的升力面理论设计方法,并使用该方法与忽略桨毂作用的设计方法分别对某船进行螺旋桨实例设计,比较两设计方案的几何形状、水动力系数以及压力分布。预报结果表明,在升力面设计中考虑桨毂作用对螺旋桨的水动力系数无明显影响,但其压力分布与设计目标更为吻合,同时有助于降低外半径导边处载荷,有利于推迟空泡初生。The hub effects are usually ignored in the propeller lifting-surface design based on potential flow theory,the circulation of root is constrained to zero,and the hub is neglected when dealing with boundary value problems.Herein,the theoretical design method of propeller considering hub effects was established by coupling image method of two-dimensional flow problem with lifting-surface design method.Two propellers were designed for a ship by the methods with and without consideration of hub effects respectively,the geometrical shapes,hydrodynamic coefficients and pressure distributions of two propellers were compared.It is shown that hub effects in lifting-surface design has no obviously influences on hydrodynamic coefficients,but the pressure distributions of the propeller designed by the method considering hub effects is in better agreement with design goals.At the same time,considering hub effects could help to reduce loading of leading edge in external radius,that would be beneticial to postponing cavitation inception.
