Numerical Study of Vanadium Redox Flow Battery Designed with and without Flow Fields

Q. Wang [1], Z. Jiang [1], D. Lu [1], Z. Qu [1]
[1] The College of Energy & Power Engineering, Xi’an Jiaotong University, Xi’an, China

A 3D (three-dimensional) model of a vanadium redox flow battery (VRFB) with interdigitated flow channel design is proposed to study the distributions of fluid pressure, electric potential, current density and over-potential during operation. The performance of a VRFB with and without ... Mehr lesen

[1] 同济大学，上海，中国

A new method is proposed to study battery thermal behavior under nature convection condition, especially focusing on temperature rising and inhomogeneity of battery. Using porous electrode theory, an electrochemical and homogenization heat source thermal coupling model and an ... Mehr lesen

Numerical Simulation of Acoustic Properties of Porous Metals under High Sound Pressure Level Conditions

B. Zhang [1], X. Wang [1], L. Ni [1]
[1] School of Mechanical Engineering, Ningxia University, China

The sound propagation and absorption properties in porous media under high sound pressure level conditions have been reported elsewhere. Also several analytical and semi-analytical solutions have been developed; however, these solutions are relatively complicated and the provided results ... Mehr lesen

CBM Extraction System Simulation Research

X. Mingjing [1]
[1] China University of Mining and Technology, Xuzhou, Jiangsu, China

Coal mines in many countries which rely heavily on fossil energy have huge CBM, coal bed methane, reserves. Meanwhile, methane extraction efficiency of low permeability coal seam is very low. It causes seriously waste of low-carbon energy source. For the sake of enhancing the efficiency ... Mehr lesen

Numerical Simulation of Quasi-steady-state Gas Flow in a Landfill

Q. Zheng [1],
[1] Zhejiang University, Hangzhou, Zhejiang, China

Landfill is currently the most dominating method to dispose wastes, which are caused by the lives of residents and constructions of cities and towns. Because of large amounts of organic substances in landfills, they will undergo continuous microbial degradation, which generates a lot of ... Mehr lesen

Silicon Nanopillar Array for Light Emission Enhancement in Color-converting LED

P. Ding （丁佩） [1],
[1] Department of Mathematics and Physics, Zhengzhou Institute of Aeronautical Industry Management, Zhengzhou, Henan, China

Plasmonic metallic nanostructures have been demonstrated an effective way to enhance the light emission efficiency in LEDs. Here, we propose a design of white LEDs that combining dielectric silicon nanopillar array in the color-converting layer. By investigating theoretically the guided ... Mehr lesen

Study of the Anomalous Reflection from the Ultra-thin Metallic Nano-strip Antenna

胡德骄 [1], 庞霖 [1], 杜惊雷 [1],
[1] 四川大学，成都，四川，中国

Introduction: A metal film whose thickness is smaller than the skin depth, is of high transmission in the visible and half-transparent in the near infrared. However, when the film is divided into discrete nano-strips (i.e. array), an enhanced anomalous reflection and suppressed ... Mehr lesen

基频最大的经纬仪基座的拓扑优化

高阁 [1][2], 刘震宇 [1],
[1] 中国科学院长春光学精密机械与物理研究所，长春，吉林，中国
[2] 中国科学院大学，北京，中国

In order to satisfy the requirements of modern range measuring technology, photoelectric theodolites gradually develop towards lightweight and minitype design. As a consequence, the mobile theodolite is becoming a hot spot recently. New requirements are raised for the theodolite base ... Mehr lesen

AlGaInAs/InP Hexagonal Resonator Microlasers with a Center Hole

H. Weng [1], Y. Yang [1], B. Liu [1], X. Ma [1]
[1] Institute of Semiconductors, Chinese Academy of Science, Beijing, China

In the past decades, equilateral polygonal microcavity lasers with whispering-gallery modes (WGMs) have attracted great attentions due to their potential application in photonic-integrated circuits. Compared to the perfect microdisk without deformation, the polygonal microcavities such ... Mehr lesen
