【摘要】 随着国际上石油价格飞涨,能源短缺,特别是MEPC第58次会议发布EEDI计算公式以及MEPC第62次会议正式通过《MARPOL73/78公约》附则Ⅵ修正案,世界各国都认识到了船舶节能减排的重要性。船舶节能技术得到广泛的关注。相比于节能新船型和新型高效推进器,附加水动力节能装置无疑是一种成本低廉、见效显著、安装方便的节能选择。通过合理搭配2个或多个不同附加水动力节能装置,充分利用各自的水动力特性可以得到更好的节能收益。本文主要介绍基于导管类的附加水动力组合节能装置、基于导流鳍的附加水动力组合节能装置、基于扭曲反应舵的水动力组合节能装置,并分析各节能装置的节能原理与节能效果等。更多还原

【Abstract】 The countries all-around the world have recognized the importance of marine energy conservation,and the techniques of ship propulsion and its energy-saving has been widely focused during the up-trend prices of ship fuel oil,and the shortage of energy,especially the formula of EEDI was given in the 58 th conference of MEPC, and the annex Ⅵ amendment of MARPOL 73 /78 PROTOCOL was formally adopted in the 62 nd conference of MEPC. Compared with new energy-saving type of ship and highly efficient propeller,hydrodynamic energy-saving appendages is undoubtedly a kind of low cost,effective significant,convenient installation energy-saving choice. We can get better energy-saving benefits by combining two or more different kinds of hydrodynamic energy-saving appendages. The research and development of the hydrodynamic compounded energy-saving device were introduced in this paper,such as the hydrodynamic compounded energy-saving device base on ducts,the hydrodynamic compounded energy-saving device base on fins,the hydrodynamic compounded energysaving device base on twisted rudder,and then the principle and effect of the hydrodynamic compounded energy-saving device was analyzed.更多还原
