摘　　要：为了获得船舶最佳节能效果,螺旋桨前置预旋节能定子的参数化设计很有必要。本文基于升力面理论与CFD数值模拟,对模型尺度下的某10 000 TEU集装箱船的自航性能进行了数值模拟和节能定子优化设计。通过改变定子叶片的偏转角度,获得了不同形式的定子,并分别计算了各种定子形式下的自航因子。同时采用升力面方法计算了自航状态下各定子与螺旋桨的数值环量,分析了船身效率、相对旋转效率及推进效率随定子与螺旋桨环量比的变化趋势。通过比较不同定子形式下螺旋桨的推进效率,得出了预旋定子相对螺旋桨环量的最优环量比值范围在70%～80%,为定子的优化设计提供了理论依据。To optimize the energy-saving effect of a ship,it is necessary to develop a parameterized design method for a pre-swirl stator before a propeller.This paper presents numerical simulations on the self-propulsion performance of a 10 000 TEU container vessel at model scale and optimization of energy-saving stators based on the lifting-surface theory and computational fluid dynamics(CFD)method.Various forms of stators were derived by changing the stator blade deflection angle,and the self-propulsion factors corresponding to various forms of stators were derived by calculations.In addition,the numerical circulations of stators and propellers under the self-propelled state were calculated by the lifting-surface theory,and the tendency of hull efficiency,relative rotational efficiency and propulsive efficiency to change with the circulation ratio of stator to propeller was analyzed.By comparing the propulsion efficiency of different forms of stators,the optimal circulation ratio of pre-swirl stator relative to the propeller is found to be within 70%~80%,which can provide a theoretical basis for the optimal design of stators.
