摘要
船舶行业的节能技术研究,是当今的一个热点,气体润滑减阻技术就是其中的一个分支。该文以平板模型为研究对象,以在空泡水筒完成的气体润滑减阻原理性验证试验为基础,展开数值计算中VOF模型和Mixture模型在此类问题中的适用性研究,分析喷气量对减阻率和气穴内空隙率分布的影响,建立了一种适用于气体润滑减阻问题的数值计算方法。
The air-lubrication drag reduction is one of the hotspots in energy saving technology research of shipping industry area. In this paper the plate model is studied by air-lubrication drag reduction proof test in CSSRC, cavitation tunnel. The applicability oriented numerical calculation approach is based on the VOF model and Mixture model. Considering the influence on drag reduction efficiency and voidage distribution in the air cavity caused by air flow rate, a numerical method is set up to the air-lubrication drag reduction issues.
