| 1 | Laminar flow of micropolar fluid in rectangular microchannels显示文摘与宏规模上的经典流动相比,在微隧道的流动有象磨擦增加和流动率减小那样的一些新现象。使用微极的液体解释这些现象的 Papautsky 和同事当模特儿在哪儿效果液体分子微旋转被考虑。但是速度向量的卷屈和向量在笛卡儿的坐标然后微旋转的旋转向量不正确地被给的微旋转的旋转的卷屈在 z 方向有仅仅一个部件。而且,微旋转的旋转向量的分叉的坡度术语在尖时刻方程不正确地被错过。在这篇论文,为在矩形的微隧道的微极的液体的 laminar 的管理方程被重建。速度侧面和微旋转的旋转的数字结果被一个过程基于 Chebyshev 搭配方法获得。速度和微旋转的旋转上的微极的效果详细被讨论。 | Shangjun Ye Keqin Zhu W.

| 2 | Numerical and experimental research of flow control on an NACA 0012 airfoil by local vibration显示文摘A flow control technique by local vibration is proposed to improve the aerodynamic performance of a typical airfoil NACA 0012. Both wind-tunnel experiments and a large eddy simulation(LES) are carried out to study the effects of local vibration on drag reduction over a wide range of angles of attack. The application parameters of local vibration on the upper surface of the airfoil are first evaluated by numerical simulations.The mounted position is chosen at 0.065–0.09 of chord length from the leading edge.The influence of oscillation frequency is investigated both by numerical simulations and experiments. The optimal frequencies are near the dominant frequencies of shear layer vortices and wake vortices. The patterns of shear vortices caused by local vibration are also studied to determine the drag reduction mechanism of this flow control method. The results indicate that local vibration can improve the aerodynamic performance of the airfoil. In particular, it can reduce the drag by changing the vortex generation patterns. | Bin LOU Shangjun YE Gaofeng WANG Zhilong HUANG | 2019 | Applied Mathematics and Mechanics(English Edition)2019，40，1： | 4 |
| 3 | Nanocomposites of CsPbBr_(3) perovskite quantum dots embedded in Gd_(2)O_(3):Eu^(3+) hollow spheres for LEDs application显示文摘Gd_(2)O_(3):Eu^(3+)@CsPbBr_(3) quantum dots(QDs)mesoporous hollow nanocomposites with good luminescent properties and high stability were built.Among which,the hollow Gd_(2)O_(3):Eu^(3+)spheres and CsPbBr_(3) QDs were prepared by urea homogeneous precipitation and hot-injection method,respectively.Finally,the Gd_(2)O_(3):Eu^(3+)@CsPbBr_(3) QDs shell-core compounds were constructed through mechanical stirring.The structure,morphology,stability and luminescent properties were studied by Fourier transform infrared spectroscopy(FT-IR),differential scanning calorimetry/thermogravity(DSC/TG),X-ray diffraction(XRD),field-emission scanning electron microscopy(FE-SEM),transmission electron microscopy(TEM),photoluminescence excitation/photoluminescence(PLE/PL)and life decay tools.Compared to the original CsPbBr_(3) QDs,Gd_(2)O_(3):Eu^(3+)@CsPbBr_(3) QDs display better photostability,thermal stability and current stability.The resulting Gd_(2)O_(3):Eu^(3+)@CsPbBr_(3) QDs composite exhibits good yellow emission.The Gd_(2)O_(3):Eu^(3+)@CsPbBr_(3) QDs mixed silicone resin was directly coated on the blue LED chip,then the w-LED device with the color coordinate of(0.31,0.32)was successfully assembled.The Gd_(2) O_(3):Eu^(3+)@CsPbBr_(3) QDs compounds with excellent luminescent properties and stability are expected to be widely used in lighting and display areas. | Gang Wang Shangjun Yu Bin Liu Zongming Liu Jinkai Li | 2022 | Journal of Rare Earths2022，40，10： | 3 |
| 4 | Multi-objective optimal allocation strategy for the energy internet in Huangpu District, Guangzhou, China显示文摘To improve the overall efficiency of the energy system,the basic structure for the energy internet of coordination and optimization of“generation-grid-load-storage”of Huangpu District,Guangzhou,China is designed,while the arrangement for the output of centralized and distributed energy module and energy storage are proposed.Taking economic benefit maximization,environmental benefit maximization and energy efficiency maximization as sub-objectives,the mathematical model of multi-objective optimal allocation and operation strategy of the energy internet is established considering supply-demand balance constraints,equipment characteristic constraints,operation mode constraints,and energy conditions constraints.The calculation results show that without considering the outsourced electricity,the balanced strategy,the economic development strategy,the environmental protection strategy,and the energy efficiency strategy are obtained by calculation,which are all superior to the traditional energy supply strategy.Moreover,considering the outsourced electricity,the proportion of outsourced electricity to total electricity is 19.8%,which is the system optimization of the energy internet under certain power demand.Compared with other strategies without outsourced electricity,the outsourced electricity strategy can have a certain emission reduction effect,but at the same time reduce the economic benefit.Furthermore,the huge difference in demand for thermal and cooling load between industrial and commercial areas results in the installed capacity of gas distributed energy stations in industrial areas being nearly twice as large as that in commercial areas.The distributed photovoltaic power generation is allocated according to the proportion of the installed roof areas of photovoltaic power generation system in residential,industrial,and commercial areas. | Pei LI Guotian CAI Yuntao ZHANG Shangjun KE Peng WANG Liping GAO | 2020 | Frontiers in Energy2020，14，2： | 2 |

| 11 | Ultrasound-assisted co-precipitation synthesis of mesoporous Co_(3)O_(4)–CeO_(2)composite oxides for highly selective catalytic oxidation of cyclohexane显示文摘The one-step highly selective oxidation of cyclohexane into cyclohexanone and cyclohexanol as the essential intermediates of nylon-6 and nylon-66 is considerably challenging.Therefore,an efficient and low-cost catalyst must be urgently developed to improve the efficiency of this process.In this study,a Co_(3)O_(4)–CeO2 composite oxide catalyst was successfully prepared through ultrasound-assisted co-precipitation.This catalyst exhibited a higher selectivity to KA-oil,which was benefited from the synergistic effects between Co^(3+))/Co^(2+))and Ce^(4+)/Ce^(3+)redox pairs,than bulk CeO2 and/or Co_(3)O_(4).Under the optimum reaction conditions,89.6%selectivity to KA-oil with a cyclohexane conversion of 5.8%was achieved over Co_(3)O_(4)–CeO2.Its catalytic performance remained unchanged after five runs.Using the synergistic effects between the redox pairs of different transition metals,this study provides a feasible strategy to design high-performance catalysts for the selective oxidation of alkanes. | Shangjun Fu Kuiyi You Zhenpan Chen Taobo Liu Qiong Wang Fangfang Zhao Qiuhong Ai Pingle Liu He’an Luo | 2022 | Frontiers of Chemical Science and Engineering2022，16，8： | 1 |
