在微波加热的多物理场仿真中,如果被加热物体的几何区域太小或者太薄,会造成整个模型网格剖分困难、网格数量多且计算消耗内存大等问题。本文针对微波加热时薄壁容器的网格剖分困难,网格数量大,且占用计算机内存资源多的问题,提出了一种基于变换光学算法的微波薄壁加热模型计算优化方法。利用变换光学算法将薄壁区域空间扩大,通过改变薄壁区域内的介质参数来与原模型进行空间映射,从而避免网格剖分过程中的薄壁问题出现,这样可以在同样的网格剖分设置下减少整个模型的网格数量,节省计算时间,减少计算机内存资源的占用。通过相应的公式推导,在二维模型中实现了薄壁变换光学算法的计算 ... Read More
Microwave drying of fruits and vegetables in a domestic oven has been found to result in large textural changes in the product such as puffing, crack formation and even burning due to the inhomogeneous heating of the microwaves. Microwave drying of potatoes is a complex interplay of ... Read More

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。 Read More
Magnetic Suspension and Balance Systems (MSBS) are a method of levitating an aerodynamic model in a wind tunnel. An unusual characteristic is that the electromagnet assemblies (outside the wind tunnel) are very large, but the levitated object (a permanent magnet core) is quite small and ... Read More
Resistance-sintering can be used in a powder metallurgy process as the heating step to consolidate a metallic compact previously obtained by pressing a powder-alloy. This fast-sintering process consolidates electrically conductive powders by simultaneous application of pressure and ... Read More
