摘要
随着国际航运减排新规和国内“双碳”战略的实施,船舶气体润滑减阻作为一种新型船舶节能降碳技术,备受航运与船舶工业关注。目前,根据气体润滑的减阻机理及其两相界面形态,主要可将其分为连续气层减阻与离散气泡减阻。文中分别介绍连续气层减阻与离散气泡减阻的国内外实船应用现状,重点对气体润滑的实船布置、形式、减阻和节能效果等进行综述,并根据已有实船应用中报道的净节能情况,对气体润滑减阻船舶的节能与降碳效果进行分析。最后,对气体润滑减阻在实船应用中面临的技术挑战及值得深入研究的方向进行简要展望。
With the implementation of new carbon reduction rules for international shipping,as well as the domestic"peak carbon and carbon neutrality"strategy,the innovative air lubrication drag reduction technology for ship energy-saving and carbon reduction has recently attracted increasing attention in the shipping and shipbuilding industries.At present,according to the drag reduction mechanism and two-phase interfacial morphology,air lubrication can be divided into continuous air layer drag reduction and dispersed bubble drag reduction.We introduce the application status of continuous air layer drag reduction and dispersed bubble drag reduction both at home and abroad.An overview of the layout,form,drag reduction and net energy-saving of ship air lubrication is provided.The energy-saving and carbon reduction benefits of ship air lubrication are then discussed based on the reported data.Finally,brief predictions are made for the technical challenges and directions worthy of further research in the application of air lubrication.
