Abstract

Bionic non-smooth surfaces inspired by the denticles of sharkskin has become one of most important research over the world. Riblet drag reduction is one of the methods inspired from nature and has been achieved relatively good results in engineering. However, continuous fabricating large-area riblet surface is still a serious challenge. In this paper, superior functions surface with continuous large area micro riblet is fabricated by Micron/Nano imprinter. The riblet of Polyester film exhibits excellent morphology feathers, the spacing and height of the riblet are 25 and 8 μm, respectively. The riblet surface exhibits ~3% drag reduction at the velocity is 3 m/s. Furthermore, the computational fluid dynamics method is employed to explore the mechanism of micro riblet surface in drag reduction. This study could enlighten the strategy for large-area manufacturing and practical industrial application of bionic micro riblet.
