船舶推进节能技术研究与进展

随着船舶燃油价格的上涨,船舶节能技术得到了广泛的关注,本文旨在介绍国内外船舶推进与节能方面的研究与进展。其中包括优秀船型的研究、开发附加流体水动力节能装置、新型高效推进器以及一些特殊船舶节能技术的研究。重点介绍了非对称尾船型、双尾鳍船型、可调距螺旋桨、对转螺旋桨、桨后自由旋转助推叶轮、舵附推力鳍以及一些特殊船舶推进节能装置的研究与应用等。

Research and development of ship propulsion and marine energy saving

The techniques of ship propulsion and its energy saving gets more and more attention during the up-trend of ship fuel oil. The research and development of the ship propulsion and marine energy saving techniques were introduced in this paper, such as outstanding type of ship, hydrodynamic energy saving appendages, new type propeller and some other particular ship energy saving devices. This paper emphasis on the asymmetry tail ship, double tail ship, pitch control propeller, contrary-turning propeller, free rotating impeller wheel, rudder with additional thrust fins and some particular energy saving devices.
