摘　　要：前置预旋定子设计的关键是该定子设计环量的选取,这直接关系到它的节能效果。以一艘7万吨级散货船为例,应用升力线理论引入环量加权因子,借助CFD性能预报分析前置预旋定子设计环量对节能效果的影响,并获得最佳设计环量。在水池进行了快速性对比试验。试验结果验证了设计方法的可行性,按最佳设计环量加权因子设计的前置预旋定子在设计点可节能4.54%,效果显著。The design circulation of a pre-swirl stator is a key factor determining its final energy saving effect. Based on lifting line theory and CFD numerical method, optimum design circulation of a pre-swirl stator is investigated for a 70000DWT bulk carrier. With introduction of weighting coefficient for design circulation, an optimum circulation for the pre-swirl stator is obtained with tradeoff between propulsion efficiency and resistance. A comparison of towing tests between models with and without pre-swirl stator shows that the pre-swirl stator with optimum design circulation has energy saving effect up to 4.54%.
