| 1 | NUMERICAL SIMULATION AND EXPERIMENTAL STUDY OF DRAGREDUCING SURFACE OF A REAL SHARK SKIN显示文摘It is well known that shark skin surface can effectively inhabit the occurrence of turbulence and reduce the wall friction, but in order to understand the mechanism of drag reduction, one has to solve the problem of the turbulent flow on grooved-scale surface, and in that respect, the direct numerical simulation is an important tool. In this article, based on the real biological shark skin, the model of real shark skin is built through high-accurate scanning and data processing. The turbulent flow on a real shark skin is comprehensively simulated, and based on the simulation, the drag reduction mechanism is discussed. In addition, in order to validate the drag-reducing effect of shark skin surface, actual experiments were carried out in water tunnel, and the experimental results are approximately consistent with the numerical simulation. | ZHANG De-yuan LUO Yue-hao LI Xiang CHEN Hua-wei | 2011 | Journal of Hydrodynamics2011，23，2： | 17 |
| 2 | 仿生制造的生物成形方法显示文摘生物制造与仿生制造是机械领域与生物领域交叉产生的新领域。生物方式制造是利用生物手段的制造方法,已提出生物去除加工、生物约束成形、生物生长成形、生物连接成形、生物复制成形、生物自组织成形等加工成形方法。仿生制造是模拟生物形体与功能的结构制造,包括仿生材料结构、仿生表面结构、仿生运动结构等结构制造。仿生制造的结构往往比较复杂,利用增材快速原型和传统机械制造方法效率通常较低,利用生物方式制造方法往往更加简便和快捷。阐明生物成形方法在仿生微纳复杂形体、结构、功能界面制造上的优势,表明生物成形技术在节能、环保、微纳等领域具有广阔的应用前景。 | 张德远 蔡军 李翔 姜兴刚 韩鑫 陈博 | 2010 | 机械工程学报2010，46，5： | 14 |

| 4 | High-precision bio-replication of synthetic drag reduction shark skin显示文摘Nano-long chains were grafted over the replicated micro-grooves of shark skin in a novel attempt to replicate bio-synthetic drag reduction structure with high precision through synthetic bio-replication. Pre-treated shark skin was used as casting template to prepare a flexible female die of silicone rubber by soft die formation. A waterborne epoxy resin was then used to graft long-chains of drag reduction agent and prepare a synthetic drag reduction shark skin with nano-long chain drag reduction interface and lifelike micro-grooves. Replication precision analysis shows that this technology could replicate the complicated three-dimensional morphology of a biological drag reduction surface with high precision. Drag reduction experiments show that the material had an excellent synthetic drag reduction effect, with a maximal drag reduction rate of up to 24.6% over the velocities tested. | ZHANG DeYuan LI YuanYue HAN Xin LI Xiang CHEN HuaWei | 2011 | Chinese Science Bulletin2011，56，9： | 13 |
| 5 | Advances of drag-reducing surface technologies in turbulence based on boundary layer control显示文摘Our living environment is surrounded by turbulence, which is also a concern of the global energy consumption and the greenhouse gas emission, and the viscous force on the solid-liquid/solid-gas interface is an important part of the turbulence. Reducing friction force in turbulence to the greatest extent is becoming an urgent issue to be resolved at present. In this paper, the various state-of-the-art approaches of drag-reducing and energy-saving technologies based on the boundary layer control are reviewed, focusing on the polymer drag reduction additives, the micro-morphology, the super-hydrophobic surface, the micro air bubbles, the heating wall, the vibrant flexible wall and the composite drag reduction methods. In addition, the mechanisms of different drag reductions based on the boundary layer control and the potential applications in fluid engineering are discussed. This paper aims not only to contribute to a better understanding of drag reduction mechanisms, but also to offer new perspectives to improve the current drag-reducing and energy saving technologies. | LUO Yuehao WANG Liguo GREEN Lork SONG Kenan WANG Liang SMITH Robert | 2015 | Journal of Hydrodynamics2015，27，4： | 8 |

| 12 | Fabrication of a micro-structured surface based on interfacial convection for drag reduction显示文摘Based on interfacial convection in the presence of solvent evaporation, a novel method for the fabrication of a micro-structured surface is proposed to facilitate drag reduction. A mixture was coated on a substrate through a specially developed spray-painting system. Micron scale pits formed spontaneously in the coated surface because of interfacial convection and deformation driven by the gradient of the interfacial tension. Experimental results indicated that particles in the mixture played a crucial role in pit for-mation, and with a suitable selection of particle size and dosage, the characteristic parameters of the pitting could be controlled. The drag reduction experiments were first performed in a water tunnel, and the results showed that the micro-structured surface had a remarkable drag reduction performance over a great range of flow speeds. | DOU ZhaoLiang WANG JiaDao YU Feng CHEN DaRong | 2011 | Chinese Science Bulletin2011，56，7： | 1 |
