Keynote Talk: Upgrading Synchroton Light Sources with COMSOL Server™

N. Goldring [1]
[1] RadiaSoft, LLC., Boulder, CO, USA

Next-generation synchrotron light sources are creating orders-of-magnitude brighter X-rays by reducing horizontal emittance. This requires the bending magnet pole tips to be closer to the electron beam axis, which in turn requires smaller vacuum chambers. The resultant design challenges ... Saiba Mais

熔喷是工业上用于制备微米纤维非织造布的一种工艺方法。在熔喷过程中,高聚物熔体经过高速、高温气流的拉伸,在接受装置上固化结晶形成微米纤维非织造布。由于熔喷材料具有很高的比表面积,因而具备良好的过滤性、吸附性、隔离性,可用于过滤材料、隔离材料、吸纳材料、口罩材料等领域。熔喷材料的优异性能是基于熔喷纤维的微纳米级的尺度,降低纤维的直径有利于提高熔喷产品的性能。由于纤维的拉伸细化发生在气流场的运动过程中,因此对纤维运动的研究具有重要意义。本研究将高聚物与气流所形成的混合体系作为两相流来处理。我们采用Comsol multiphysics 的水平集方法对熔喷过程的高聚物 ... Saiba Mais

在电池的性能比较过程中总存在温升、恒流比、容量保持率、倍率性等电性能比较,其中影响这些性能的重要参数就是电池的极化大小。然而现实使用中极化很难以量化,仅仅用直流或者交流内阻来表示还显得单一且不具有说服力,所以寻求一种能够量化的手段从而来衡量电池的极化具有重要意义。通过极化的占比分析还可以分析哪一种极化影响较大,从而为电池的设计优化提供可靠的方向指导。 鉴于上述描述,我们开发了一种充放电过程中极化仿真方法及模型。在COMSOL® 软件的一维模型中定义编辑正负极以及隔膜电解液处反应极化方程和积分,然后利用“电池与燃料电池模块 ... Saiba Mais

复合无间隙氧化锌避雷器是保护电力系统中各种电气设备安全稳定运行,免遭操作过电压和大气过电压侵害的重要装置。而其外部硅橡胶绝缘材料长期承受不均匀电场,导致外部绝缘材料加速劣化,对避雷器本体的安全性能造成威胁,为此,通过建立110KV复合无间隙ZnO避雷器的仿真模型,分析其外部绝缘材料空间场强分布情况,提出使用非线性电导材料对端部分布不均匀的高场强区域进行局部替换。采用COMSOL软件建立二维轴对称模型,利用AC/DC模块对避雷器进行仿真。仿真结果表明,使用非线性电导材料替换后,沿避雷器伞裙外表面最大场强从1.21 MV/m分别降至0.67MV/m、0.86MV/m ...

In this work, we investigate the resonant properties of finite-sized membrane-mass-type elastic metamaterial thin plates. We find that the effective bending stiffness of such metamaterial thin plates can be controlled independently by the out-of-plane rotational resonances, so as to vary ... Saiba Mais
