We present a detailed 2D COMSOL Multiphysics® model used to determine and improve the conversion efficiency in a liquid-metal microfluidics-based portable energy transducer. To date, most work on power generation technologies has focused on the optimization of existing technologies, and ... Mehr lesen
The dynamics of phase slip centers in a 1D model of superconducting wire was created based on the set of time-dependent Ginzburg-Landau equations (TDGL). The General Form PDE interface of COMSOL Multiphysics® simulation software was used. TDGL has successfully applied to this problem ... Mehr lesen
An important attribute for numerical simulations is to provide accurate quantified solution values. Thus it is useful to find complex problems with analytic solutions to confirm the numerical results obtained from software. The well-known proximity effect causes a redistribution of ... Mehr lesen
Power Transformers are the most important piece of power system elements and protecting this device from failures, especially from the internal faults has been a major challenge. The internal faults such as Turn-to-Turn (T2T) and Turn-to-Ground (T2G) has been attributed to most of the ... Mehr lesen
Photothermal deflection spectroscopy (PDS) relies on the angular displacement of a probe beam through a fluid with varying index of refraction. The precise angular displacement of the probe beam is dependent on the entire index of refraction field, which is in turn dependent on fluid ... Mehr lesen
CT and MRI are current techniques used for stroke detection. Although they are favored for their high accuracy and resolution, there are many situations that a potable and low-cost imaging technique is required. Ultra-sound technique is portable, but it cannot be used for stroke ... Mehr lesen
At the moment of DC activation, charged surfaces begin interacting with the adjoining electrolyte solution. The charges along the surface of that interface slowly attract oppositely charged ionic particles, which eventually gather on or near the surface, creating the Electric Double ... Mehr lesen
The quantitative value of electrical bio impedance in tissue structures is sensitive to changes in ionic concentration, frequency and dispersion but lacks specificity. It is difficult to a create a physical measurement set up of clinical value capable of quantifying the contribution of ... Mehr lesen
钻井时,泥浆滤液会在压力差的作用下侵入到渗透性地层,地层水的饱和度与矿化度发生改变,从而测量的电阻率数值偏离地层电阻率。 长方体模拟地层，三个圆分别模拟供电和测量电极，参数设定坐标。 地下水流模块中Two-Phase Darcy’s Law接口模拟泥浆侵入，两相流体密度和黏度，固体孔隙度与绝对渗透率都通过空白材料赋值，地层上下无流动，设定地层初始压力和流体饱和度，左侧边界设定侵入压力和流体饱和度，右侧边界设定出口压力。 化学模块中的Transport of diluted species in porous media计算泥浆侵入后地层水矿化度 ... Mehr lesen
高温超导磁悬浮现象自发现以来,以其独特的无源自稳定优势被广泛应用于超导轴承、飞轮储能和轨道交通等领域。随着高速磁悬浮应用的发展和需求，关于高温超导磁悬浮在动态运行下的悬浮特性研究变得尤为重要。本文借助COMSOL Multiphysics软件，耦合AC/DC模块和传热模块，基于磁场强度H法和非线性幂指数E-J关系，建立了悬浮于环形永磁轨道上方的高温超导块材三维实体模型。通过设置轨道的上下振动来模拟超导块材高速运行下受到的轨道不平顺带来的交变磁场的影响。仿真以高温超导块材磁-热-力耦合特性为切入点，研究了在变化外磁场下超导块材悬浮性能及其内部温度变化情况 ... Mehr lesen
