国内外船舶气体减阻技术应用进展

Application of Air Lubrication Drag Reduction Technology at Home and Abroad

介绍船舶气体减阻的机理、气泡发生方式、形成机制以及影响因素,同时分别介绍气泡减阻与气层减阻的国内外主流研究机构及其商业化实船应用现状。指出国内外气体减阻应用存在差距,气泡减阻较气层减阻更为成熟,并针对这一应用现状,提出气泡减阻与气层减阻在应用中所应注意的问题。

The technical principle of the ship air lubrication drag reduction,the generation mode,the formation mechanism of the bubble,and the influencing factors are introduced in the current study.The state-of-art of the current domestic and the foreign research institutions for the bubble drag reduction and the air layer drag reduction,and their commercial full-scale ship applications are also introduced respectively.It points out that there is a gap in the applications of the air lubrication drag reduction technology at home and abroad,while the bubble drag reduction is more mature than the air layer drag reduction.The problems that should be paid attention to in the application of the bubble drag reduction and the air layer drag reduction are put forward according to the current application status.
