Induction furnaces are employed for vacuum distillation process to recover heavy metals after electro-refining operation. Induction furnace of suitable heating rate and cooled by passive means are required to be developed for this purpose. It is planned to set up a mock up induction ... Mehr lesen
MW heating acts on asbestos fibers in slates and degrade them at low temperature comparing with conventional heating methods. The simulation of comsol multiphysics makes important roles to investigate the degrading mechanism, and will be introduced at the conference. We introduce the ... Mehr lesen
Electromagnetic sounding measurements utilize magnetic induction to constrain the interior geophysical properties of planetary bodies. Under some conditions, the Earth’s moon can be approximated by the response of a conducting sphere in a vacuum. Transient magnetic fields originating ... Mehr lesen
Partial differential equations (PDEs) govern many phenomena in nature. Solving optimization problems which comprises the solution of large number of PDEs, is expensive concerning time and memory. Therefore, to reduce the solution cost, original problem is transformed to a corresponding ... Mehr lesen

在电磁兼容领域中,除了电磁干扰还会存在毁灭性的电磁辐射危害。其中电磁辐射对燃油危害的研究关键在于掌握射频放电的击穿特性,为研究不同频率的击穿特性,本文基于电磁场和电路理论,以飞机油箱口结构为例构建了氩气射频放电前后的等效电路模型,并简要分析了射频放电规律。根据电磁场和电路理论,飞机油箱口放电结构等效为圆柱型交流电容,等效电路的并联电阻阻值随气体的导电性能变化而变化,能有效表征气体击穿电离程度的高低。仿真研究表明,相同激励电压条件下,频率越高,气体越容易击穿,等效并联电阻阻值越低。气体击穿电离程度随频率升高存在不连续放电、连续稳定放电、积累效应和雪崩效应四种不同的放电规律。 Mehr lesen

电磁辐射对燃油危害是加油站、炼油厂、油气基地等大型设施禁用手机和其他无线通讯设备的重要原因。不同于静电对燃油蒸气的危害,本文的研究重点在于分析不同频率下的射频放电击穿特性。基于射频等离子体鞘层模型,通过多物理场仿真,分析了12M~300MHz频率下的氩气射频放电过程。仿真结果表明,当激励频率大于雪崩击穿临界频率时,两侧极板附近会形成随激励周期变化的鞘层区,中心区域为准电中性的等离子体区。同时,当激励频率远小于等离子体频率时,鞘层会促进极板附近的γ电离过程;随着频率增大,鞘层特性会逐渐退化,而中心区域的α电离过程会增强。此外,放电特性曲线表明,频率越高,板间放电电压越小 ...
