| 1 | 顶吹两相流影响熔池搅拌效果的水模型实验研究显示文摘主要针对艾萨熔炼体系中贫化电炉的浸没式油气混合顶吹喷枪对熔池的搅拌效果影响进行实验。设计并搭建了一定相似比的贫化电炉水模型平台,通过计算所得的最佳深度范围设计三喷枪混合顶吹组合实验方案。在其他实验条件,如气含率、喷吹速度等与实际生产相似的前提下,实验研究改变喷枪插入深度对搅拌效果的影响,并对各条件下的实验现象及拍摄照片进行对比。实验结果表明:当顶吹喷枪插入深度为渣层厚度的1/2~2/3时,两相流混合喷射对熔池的搅拌效果最佳,并应用于贫化电炉实际生产,取得了单枪8%以上的节油量。 | 熊靓 王华 王冲 王仕博 杨濮亦 刘泛函 | 2014 | 化工进展2014，33，7： | 9 |

| 4 | Wetting transition energy curves for a droplet on a square-post patterned surface显示文摘Due to the property of water repellence, biomimetic superhydrophobic surfaces have been widely applied to green technologies, in turn inducing wider and deeper investigations on superhydrophobic surfaces. Theoretical, experimental and numerical studies on wetting transitions have been carried out by researchers, but the mechanism of wetting transitions between Cassie-Baxter state and Wenzel state,which is crucial to develop a stable superhydrophobic surface, is still not fully understood. In this paper,the free energy curves based on the transition processes are presented and discussed in detail. The existence of energy barriers with or without consideration of the gravity effect, and the irreversibility of wetting transition are discussed based on the presented energy curves. The energy curves show that different routes of the Cassie-to-Wenzel transition and the reverse transition are the main reason for the irreversibility. Numerical simulations are implemented via a phase field lattice Boltzmann method of large density ratio, and the simulation results show good consistency with the theoretical analysis. | Wei Gong Yingqing Zu Sheng Chen Yuying Yan | 2017 | Science Bulletin2017，62，2： | 3 |
| 5 | Investigation of Droplet Evaporation on Copper Substrate with Different Roughness显示文摘In the present study,we investigated the evaporation process and deposition pattern of saline droplet on a copper substrate with different roughness under 40℃ambient temperature.These four substrates are classified as smooth surface and rough surface based on their droplet contact angles.It has been found in this study that the evaporation pattern of droplets has a strong relationship to substrate roughness.The thickness boundary of the evaporation pattern on a smooth surface is larger than that on a rough surface and the particles are closer to boundary and the tendency is more obvious on a smooth surface.The below factors contribute to the result.On the smooth surface,the contact angle of droplet increases as the roughness decreases.On the rough surface,the contact angle increases as the roughness increases.With contact angle decreasing,the evaporation rate at the boundary increases leading to the particles at the boundary more easily sedimentate.Moreover,the capillary flow is hindered by increasing the substrate roughness,while the Marangoni flow remains constant,resulting in more particles remain in the center of the droplet on the rough surface.To sum up,the coffee-ring formation is suppressed by increasing the substrate roughness on a copper substrate under 40℃temperature. | Xin Wang Zeyu Liu Li Wang Yuying Yan | 2020 | Journal of Bionic Engineering2020，17，4： | 2 |
| 6 | Bio-inspired Fog Harvesting Materials:Basic Research and Bionic Potential Applications显示文摘With the explosive growth of the world's population and the rapid increase in industrial water consumption,the world's water supply has fallen into crisis.The shortage of fresh water resources has become a global problem,especially in arid regions.In nature,many organisms can collect water from foggy water under harsh conditions,which provides us with inspiration for the development of new functional fog harvesting materials.A large number of bionic special wettable synthetic surfaces are synthesized for water mist collection.In this review,we introduce some water collection phenomena in nature,outline the basic theories of biological water harvesting,and summarize six mechanisms of biological water collection:increased surface wettability,increased water transmission area,long-distance water delivery,water accumulation and storage,condensation promotion,and gravity-driven.Then,the water collection mechanisms of three typical organisms and their synthesis are discussed.And their function,water collection efficiency,new developments in their biomimetic materials are narrated,which are cactus,spider and desert beetles.The study of multiple bionics was inspired by the discovery of Nepenthes,moist and smooth peristome.The excellent characteristics of a variety of biological water collection structures,combined with each other,are far superior to other single synthetic surfaces.Furthermore,the main problems in the preparation and application of biomimetic fog harvesting materials and the future development trend of materials fog harvesting are prospected. | Kui Wan Xuelian Gou Zhiguang Guo | 2021 | Journal of Bionic Engineering2021，18，3： | 2 |
| 7 | Enhancement of surface wettability via micro-and nanostructures by single point diamond turning显示文摘Studies on surface wettability have received tremendous interest due to their potential applications in research and industrial processes. One of the strategies to tune surface wettability is modifying surface topography at micro-and nanoscales. In this research, periodic micro-and nanostructures were patterned on several polymer surfaces by ultra-precision single point diamond turning to investigate the relationships between surface topographies at the micro-and nanoscales and their surface wettability. This research revealed that single-point diamond turning could be used to enhance the wettability of a variety of polymers, including polyvinyl chloride(PVC), polyethylene 1000(PE1000), polypropylene copolymer(PP) and polytetrafluoroethylene(PFTE), which cannot be processed by conventional semiconductor-based manufacturing processes. Materials exhibiting common wettability properties(θ≈ 90°) changed to exhibit 'superhydrophobic' behavior(θ > 150°). Compared with the size of the structures, the aspect ratio of the void space between micro-and nanostructures has a strong impact on surface wettability. | Nicolás Cabezudo Jining Sun Behnam Andi Fei Ding Ding Wang Wenlong Chang Xichun Luo Ben B.Xu | 2019 | Nanotechnology and Precision Engineering2019，2，1： | 2 |
| 8 | Simulation of the Influence of Surface Wettability on Viscous Fingering Phenomenon in Porous Media显示文摘Fingering phenomena are common occurrence in the natural world. It generally takes place when a less viscous fluid displacesa more viscous fluid typically in porous media. Nowadays, such phenomena have extensively been studied due to itsimportance in many industrial fields. In this paper, the effects of surface wettability on finger pattern are studied and simulatednumerically by the Lattice Boltzmann method (LBM). The displacement efficiency is investigated by using two parameters,namely, the breakthrough time and the areal sweep efficiency. The simulation has demonstrated that surface wettability willinfluence the finger pattern no matter the gravity is considered or not, but in the presence of gravity, the finger pattern is muchmore complicated and irregular due to the coexistence and competition of capillary force, viscous force and gravity. | B.
