摘　　要：该文采用数值计算方法,对伴流补偿导管(WED)的节能机理进行初步的探讨。研究结果表明WED不仅可以提供船舶航行所需的部分推力,还可以降低轴向伴流损失和船后尾流旋转能量损失。研究还发现,随着雷诺数的增加,WED产生的推力与螺旋桨推力的比值逐渐增大,但轴向伴流损失和船后尾流旋转能量损失则逐渐减少。In the paper, the working principles and scale effects of wake equalizing duct（WED） are researched by the numerical methods. The results show that the WED can produce the thrust for ship, and reduce the wake losses and rotating energy losses. Further on, the thrust of WED is greater on the full scale than on the model scale, and the wake losses and rotating energy losses are less oppositely.

关 键 词：节能装置(ESD) 伴流补偿导管(WED) 尺度效应 推进效率
