Lumped Element Multimode Modeling of Balanced-armature Receiver with COMSOL Multiphysics® Software

Wei Sun [1],
[1] Institute of Acoustics, Tongji University, China

For the lack of higher order modes, lumped element (LE) models currently used may be insufficient to predict the system of balanced-armature receiver (BAR). We develop a LE multimode model for BAR in the frequency domain based on the techniques of mode decomposition, truncation, and ... 詳細を見る

Lithium ion battery safety problem has attracted the whole world’s attention essentially after the explosion of Samsung Note 7. This work mainly deals with the study of the generation, characteristics and prevention measures of the battery fire. Firstly, the heat generation rate of ... 詳細を見る

A FEM Study of Displacement Sensor Based on Magnetostrictive/Piezoelectric Composite Material

Qingwei Liu [1], Hangjie Mo [1]
[1] Shanghai Jiao Tong University, Shanghai, China

This paper studies the application of laminate magnetoelectric (ME) material in displacement sensor. We studied the L-L block composite thanks to designed structure by coupling displacement signal with the displacement potential of ME composite. A nonlinear approximation is adapted to ... 詳細を見る

Low Temperature Microwave Treatment of Sphere Materials

Huangcheng Zhu [1], Youqi Deng [1], Qian Meng [1], Quansheng Wang [1]
[1] Sichuan University, Chengdu, China

Microwave heating has many advantages over the traditional heating method, such as needing shorter time, saving more energy, and being easier to control. But there still are some problems.(1) Themal runaway still exists because the reflection and absorption of microwave by the reactants ... 詳細を見る

The Metal Patch Effect on the Microwave Heating Uniformity

Huacheng Zhu [1], Qian Meng [2], Quansheng Wang [2], Youqi Deng [2],
[1] Institute of Applied Electromagnetics, Sichuan University, Chengdu, China
[2] College of Physical Science and Technology, Sichuan University, Chengdu, China

Microwave heating is known for its efficiency and instantaneity. However, the non-uniformity of the microwave heating has limited the development of its application in industry. In order to solve this problem, a metal patch sticking to the turntable was proposed. During the heating ... 詳細を見る

The Effect of Multi-Materials for Microwave Heating Uniformity

Huacheng Zhu [1], Quansheng Wang [1], Youqi Deng [1], Qian Meng [1],
[1] Sichuan University, Chengdu, China

To overcome the uneven heating during the process of microwave heating of food inside microwave oven, a geometrical model based on domestic microwave oven with a cylindrical container composed of multi-materials(with two different kinds of materials, one half is glass and the other half ... 詳細を見る

Electromagnetic Characteristics of Superconducting Coils Exposed to Travelling Magnetic Fields

Tianyong Gong [1],
[1] Southwest Jiaotong University, Chengdu, China

Two-generation superconducting coils carrying large current in alternating magnetic fields is very common in electrical applications such as HTS linear motor. So it is meaningful to study the characteristics of coated superconductors in the presence of travelling magnetic field. In this ... 詳細を見る

A Coupled Thermal, Chemical and Mechanical Model using COMSOL Multiphysics® Software

[3] Tongji University, Shanghai, China

Many numerical coupling thermo-hydro-mechanical-chemical models for methane hydrate bearing sediments(MHBS) have been proposed to analyze the mechanical behavior of MHBS during methane gas production. However, most of them are based on finite differential method (FDM) or finite volume ... 詳細を見る

A Multiscale Model of the Bipolar Electrode - SDS Adsorption on Stainless Steel

Hörmann, Johannes (何约翰) [1], Meng, Yonggang (孟永钢) [1],
[1] State Key Laboratory of Tribology, Tsinghua University, Beijing, China

In solution, sodium dodecyl sulfate (SDS) (structure shown in Fig. 1) can form a boundary film on metal surfaces. Previous studies have extensively investigated the characteristics of such surfactant films experimentally [1][2][3]. A dependency of SDS surface concentration and film ... 詳細を見る
