条纹薄膜减小湍流阻力的试验研究

The Experimental Research on Turbulent Drag Reduction with Riblets

本文从湍流边界层的相关结构出发，探讨了条纹薄膜减少湍流边界层阻力的机理，通过平板模型的水洞试验，研究了条纹薄膜的减阻作用。试验结果表明，条纹薄膜具有明显的减阻效果，最大降阻量大约为１０％。

Based on the structure of turbulent boundary layer, this paper analysises the mechanism of turbulent boundary layer drag reduction with riblets, and studies the effect of drag reduction with riblets through the experment. The experimental results show that the riblets have the obvious effect of drag reduction,the maximum drag reduction is about 10%.
