Ocean is the cornerstone in Earth’s system because the surface of the Earth is covered by ocean about 71%. Ocean also holds approximate 97% of the Earth’s water. Ocean is always moving and continuous. This study is focusing on the ocean movement in Southern Ocean which is located in the ... En savoir plus

Introduction In order to understand the detection mechanism of the PZT based nondestructive testing (NDT) technology for interface debonding of CFSTs, numerical simulation on a multi-physical model composed of surface-mounted PZT patches and CFST structural member is established in ...

Electromagnetic shearing (EMS) is a high speed sheet metal shearing system where the workpiece is fractured under a pulsed electromagnetic force. It can be regarded as an extension of electromagnetic forming[1-2]. The basic shearing principle is that a huge repulsive electromagnetic ... En savoir plus

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 ... En savoir plus

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 ... En savoir plus

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 ... En savoir plus

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 ... En savoir plus

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 ... En savoir plus

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 ... En savoir plus

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 ... En savoir plus
