叶片复合材料层的击穿是风电机组遭受雷击后的主要故障形式。对于低电导率的GFRP类叶片铺层而言，雷电先导作用下的强背景电场造成的电击穿可能先于回击电弧的热效应产生。为了获得GFRP铺层的电击穿机理，基于COSMOL Multiphysics软件，建立了引下线-GFRP铺层的流注放电数值仿真模型。考虑了空气域与介质层内部的粒子输运，以及气-固分界面上的电荷沉积与注入作用。通过“稀物质传递物理场” 模块、“静电物理场”模块、“边界常微分和微分代数” 模块以及“稳定对流-扩散方程接口” 模块对控制方程进行求解。依据电场梯度分布进行了网格加密与时间步设置 ... Mehr lesen
微波等离子体化学气相沉积技术（MPCVD）是一种用于薄膜沉积的技术，主要用于制造高质量的薄膜和涂层。这项技术包括：（1）使用微波激发等离子体（通常在2.45GHz或915MHz）。（2）等离子体中的气相反应与表面反应。（3）不同工艺参数下的沉积过程。在COMSOL案例库中“微波腔等离子体反应器”（ID:115681）该模型搭建了微波与等离子体之间的桥梁。我们希望在此基础上解决气相反应与表面反应，并对沉积过程进行初步分析。 我们模拟了这样一个状态，即在微波等离子体过程达到稳态后，利用此时的电磁参数与等离子体参数，作为化学气相沉积的初始条件与边界条件 ... Mehr lesen
在半导体增材制备的过程中，磁控溅射，使用电离的氩离子轰击靶材形成等离子气团，进而扩散转移到晶圆表面是一种常见的增材加工工艺。许多的MEMS应用和先进封装技术中常会通过偏转靶材和衬底的相对夹角进行溅射镀膜，从而形成特殊的台阶覆盖。传统来说，上述过程的工艺仿真（TCAD）往往是以变形网格耦合定向的靶材通量实现镀膜形貌的仿真；然而，变形网格的方法难以仿真封闭微腔（不连通的新域）形成，定向的靶材流体通量忽略了镀材的扩散运动在背向镀膜侧的镀材沉积。 使用COMSOL Multiphysics，我们提出了一种求解等离子体/稀释气体的流体场通量 ... Mehr lesen

Linear Induction Motor (LIM) has been identified as a key element for electromagnetic launching technology. The stator part of the motor when energized induces a linearly moving magnetic field which consequently produces a thrust force on the rotor part of the motor. Thus it accelerates ... Mehr lesen
