【摘要】 建立了高效扭曲舵水动力性能和节能效果数值评估分析方法,并针对某集装箱船设计了多个高效舵,其中有带舵球的节能装置方案,应用建立的数值方法,评估分析了高效扭曲舵节能装置的节能效果,并与试验结果进行了对比,初步验证了建立的节能效果评估方法。对高效扭曲舵的导边抬高角度对水动力性能的影响进行了分析,为高效扭曲舵的设计提供了有益指导。更多还原

【Abstract】 In this paper the numerical method to evaluate saving energy efficiency of the twisted rudder is developed,and we design some high efficiency rudders for one container ship,where some projects are twisted rudder with rudder ball.Then the analyses of saving energy efficiency are carried out with the CFD method,and compared with the model experimental results,the numerical method of evaluating saving energy efficiency of the twisted rudder is validated.The effect on hydrodynamic performance of different rising degree at leading edge is studied,the study is useful for designing high efficiency twisted rudder.更多还原
