摘要:

对一种新型的边界层控制技术-菱形网圆坑点阵结构的减阻特性进行了研究,水洞实验表明这种结构应用于NACA-16012翼型表面的减阻效果最高可达22%.

关键词: 边界层控制, 湍流减阻, 水洞实验

Abstract:

A novel boundary control technique was investigated for its drag reduction abilities, which is a special surface structrure——the concave spherical pits with arranging in the order of a rhombus. The water tunnel experiment indicated that this kind of surface structure on the NACA 16012 foil surface can reduce the flow resistance up to 22%.

Key words: boundary layer control, turbulent drag reduction, water tunnel experiment
