摘要
快速性是船舶航行的重要性能之一,新型减阻技术不断被提出推动了船舶快速性的发展。从船舶阻力原理出发,对国内外船舶减阻技术展开分析,指出当前主流研究方向为空气减阻、仿生超疏水减阻、附体减阻以及断级减阻技术;针对这4种减阻技术探究影响减阻效果的主要因素,总结当前减阻技术中存在的问题;并介绍船体加热-超声协同减阻和网状射流等新型减阻技术,对未来减阻技术的发展进行展望,为船舶减阻技术的进一步研究提供借鉴。
Rapid is one of the important performances of ships when sailing.New drag reduction technologies are constantly being proposed to drive the rapid development of ships.Starting from the principle of ship resistance,the development status of ship drag reduction technologies in China and abroad is analyzed.The air drag reduction,bionic super hydrophobic drag reduction,appendage drag reduction and stepped hull drag reduction technologies are noted as the main drag reduction technologies.The main factors affect the effect of drag reduction are explored in relation to the four drag reduction technologies,and the problems exist in the current drag reduction technologies are summarized.New drag reduction techniques such as hull heating-ultrasonic synergistic drag reduction and mesh jet are introduced,and the development trend of drag reduction technology in the future is put forward,which provide reference for further research on ship drag reduction technology.
