船舶附加水动力节能装置研究进展

Research Progress about Additional Hydrodynamic Energy- Saving Devices of Ships

综述了现有各种船舶附加水动力节能装置,包括桨前节能装置,如补偿导管、船尾导流鳍;桨后节能装置,如自由旋转助推叶轮、舵球、舵附加推力鳍;组合节能装置,如补偿导管-导流鳍-螺旋桨、导流鳍-螺旋桨-桨后自由旋转助推叶轮、导流罩-螺旋桨-舵球-舵附加推力鳍等组合式节能装置等多种形式。阐述其节能原理,并简要分析其研究、发展方向。

The research progress about three kinds of additional hydrodynamic energy-saving devices about ships has been summarized in this paper. The first classification is about paddle front energy-saving de-vices, including compensating duct, stern guide fin. The second classification is about paddle after energy-sav-ing devices, including free rotating impeller, rudder ball and rudder additional thrust fin. The final classifica-tion is about combined energy saving-devices, such as compensating duct-diversion fin, diversion fin-free ro-tating impeller, guide tube-rudder-ball additional thrust fin. Their energy conservation principles have been well interpreted. Their research and development direction have also been analyzed..
