| 摘 要： | 对减阻沟纹的形状,尤其是肋峰厚度进行了进一步优化,提出了一种由极薄的肋峰组成的细薄肋型减阻沟纹(thinbladeriblets,简称TBR);成功地制作了TBR减阻薄膜,并对其管内减阻特性进行了实验,得到了8%的减阻效果.该实验为TBR型减阻沟纹在工程实际中的应用奠定了基础.

| Abstract: | The peak shape of thin blade riblets (TBR) has a pronounced effect on drag reduction. The difficulties to manufacture the TBR film are overcome in our laboratory. Conducted experiments show a 8% reduction in drag. |
