INTRODUCTION Our group at ORNL started using COMSOL Multiphysics® software shortly after version 3.0 was released in the Spring of 2004. After 11 years and several releases, the application usage has grown along with number of licenses we are responsible for. This paper will broaden ... Per saperne di più
Microwave discharges have a wide range of applications, such as gas conversion, material processing and surface treatment; also they can provide an efficient way for dissociation of molecular gases as CO2 and N2O. Depending on the operating pressure and temperature, non-equilibrium ... Per saperne di più
Ultrasonic technology is used for various crucial measurements in the industry; few of the most popular uses are in Non-destructive testing, flow measurement, level measurement etc. Like every other energy waveform the ultrasonic waveforms also suffers attenuation while travelling ...

Due to the Paschen law the ignition voltage for plasma increases proportionally to electrode gap and pressure between electrodes. Atmospheric plasmas operating in the MHz range, being of great interest for surface treatment, require therefore high voltage power supplies, even though in ... Per saperne di più
Two different Finite Element Method (FEM) models of the CANDU® nuclear fuel channels were compared against experimental data to determine if the curvature of the fuel channels is necessary to consider for measurements of the pressure tube to calandria tube gap. The different models were ... Per saperne di più
铁芯电抗器作为电力系统中重要的基础设备之一，具有漏磁小、节省空间等优点，因此在新能源和城市配电系统中得到广泛应用。但其运行中产生的噪声严重污染周边环境，而且电抗器振动过大对其自身正常运行也会构成威胁。本文在磁致伸缩效应和麦克斯韦方程相关理论研究基础上，采用COMSOL Multiphysics®多物理场仿真软件，通过AC/DC模块、声-固模块对三相电抗器铁芯的振动噪声进行研究。首先从多物理场耦合的角度，定义瞬态计算条件，然后在瞬态磁场的基础上加上声场和固体力场来建立三维物理模型，最后通过多物理场的耦合计算，得到电抗器铁芯振动位移和声压场分布 ... Per saperne di più
微波化学反应的研究，一般要求实验装置要具有尺寸小、工作频带等特点，基于这种要求，近年来一种同轴式的微波反应器应运而生。本文基于COMSOL Multiphysics® 软件，对两种不同结构的同轴式微波反应器进行对比分析。结构主体是由外导体和内导体形成的同轴腔体，内外导体由金属材料构成可承受一定的高压反应。反应器一端为短路面，另一端结构一填充了截锥形聚四氟乙烯插件，结构二为填充了一定厚度的柱形聚四氟乙烯。我们建立了两种结构的二维轴对称模型，通过电磁波-频域接口、层流接口以及流体传热接口对其进行模拟计算，探究不同介质下反应器的加热效果。数值仿真结果如图2、图3、图4所示 ...

Convective transport of macromolecules or micro and nanoparticles in microsystems are usually predicted by solving the Navier Stokes equations for the carrier fluid and a concentration equation for the diffusing species. In the case of isolated particles or complicated geometries with ... Per saperne di più
Atomic layer deposition(ALD) is one proven method to deposit ultra-thin films. ALD is advantageous for its atomic-level thickness control and conformity; leading to high quality films. Slow deposition rates for conventional ALD contribute to the impracticality of utilization of this ... Per saperne di più
The excessive presence of residual SiC matrix inter-fiber pores is often the main cause for the very poor mechanical strength and toughness of SiC/SiC composites manufactured by CVI (Chemical Vapour Infiltration) process.
