船舶气泡减阻研究进展

Review of Research on Air Bubble Drag Reduction on Ships

船体表面气体润滑减阻技术在过去近二十年中取得了长足的进步,尤其是实船应用方面。论文全面地回顾了国内外气体润滑减阻研究的历史与现状,将气体润滑减阻技术划分为气泡减阻和气层减阻,重点介绍了气泡减阻的机理、气泡发生方式、气泡减阻理论研究和试验研究。在气泡减阻的实船应用方面,结合国内外成功案例进行分析,提出了我国发展气泡减阻技术需要进一步研究的问题。

Air lubrication drag reduction technology on ship hull surface, especially its application to the full-scale ships has been made great progress in the past 20 years. In this paper, history and current situation of research on air lubrication drag reduction at home and abroad is reviewed comprehensively. The technology of air lubrication can be divided into air bubble drag reduction technology and air layer drag reduction technology. The mechanism of air bubble drag reduction, bubble formation method, corresponding theoretical and experimental researches are introduced. Successful cases in bubble drag reduction are analyzed, and several issues for further research in this field in China are put forward.
