摘要

对于高速运动的物体来说,减少阻力一直是一个长期的重大挑战。为了解决这个问题,在过去的几十年里,人们提出了被动和消极的策略。生物与自然的融合在生物进化过程中不断完善。海洋生物独特的结构特征、材料特性和特殊功能为解决这一棘手的减阻问题提供了不竭的灵感。因此,我们提出了一种简单、低成本的激光烧蚀方法。通过控制激光路径的密度和烧蚀时间,受鲨鱼皮小齿启发制作了多尺度、多层次的波纹(MSLR)表面。使用电子显微镜和扫描白光干涉轮廓仪对其形态和地形特征进行了表征。然后,在循环水隧道中测量了仿生波纹表面的减阻能力。最后,利用计算流体动力学(CFD)方法分析了减阻机理。结果表明,随着雷诺数(Re)的增加,MSLR 表面具有稳定的减阻能力,这主要归功于 MSLR 表面形成的高低速条纹。这项研究可为在不同 Re 值下制造有效减阻的空间波纹以及改进海洋防污提供参考。

Drag reduction capacity of multi-scale and multi-level riblet in turbulent flow

Drag reduction capacity of multi-scale and multi-level riblet in turbulent flow

For high-speed moving objects, drag reduction has been a prolonged major challenge. To address this problem, passive and negative strategies have been proposed in the preceding decades. The integration of creatures and nature has been continuously perfected during biological evolution. Unique structure characteristics, material properties, and special functions of marine organisms can provide inexhaustible inspirations to solve this intractable problem of drag reduction. Therefore, a simple and low-cost laser ablation method was proposed. A multi-scale and multi-level riblet (MSLR) surface inspired by the denticles of the sharkskin was fabricated by controlling the density of the laser path and ablation times. The morphology and topographic features were characterised using an electron microscope and a scanning white-light interfering profilometer. Then, the drag reduction capacity of the bionic riblet surface was measured in a circulating water tunnel. Finally, the mechanism of drag reduction was analysed by the computational fluid dynamics (CFD) method. The results show that the MSLR surface has a stable drag reduction capacity with an increase in Reynold (Re) number which was contributed by high-low velocity stripes formed on the MSLR surface. This study can provide a reference for fabricating spatial riblets with efficient drag reduction at different values of Re and improving marine antifouling.
