摘　　要：为了实现节能的目标,提出了一种高效对转桨适伴流设计方法。首先,通过船模试验获取某集装箱船船后桨盘面处的标称伴流,对应的实船伴流则通过ITTC提供的经验公式换算获得。采用螺旋桨环流理论分别对前桨和后桨进行实桨适伴流设计,前后桨之间的相互影响通过诱导速度来考虑,且诱导速度作为伴流的一部分,采用面元法进行非定常水动力性能预报。通过实例设计分析可知:在设计进速条件下,该方法设计的对转桨同设计的单桨相比效率可提高12.09%。In order to achieve energy-saving, a wake-adapted method is developed to design highly efficient contra-rotating propellers. Firstly, the wake field at the propeller plane of a container ship is obtained through model test, and then the wake field induced by the corresponding full scale vessel is calculated by using ITTC empirical formula. Both the forward propeller and aft propeller are designed based on the theory of propeller vortex. Interaction between the forward propeller and the aft propeller is estimated through the induced velocities which are regarded as part of the wake field, and the surface panel method is utilized to predict unsteady hydrodynamic performance. It is shown through an example that, with the same design method and at the same design advance speed, the efficiency of contra-rotating propeller is 12.09 percent higher than the single propeller.
