飞机燃油系统雷电防护是飞机设计中需要考虑的一个重要部分。用实验方法研究成本较高,且周期长,数值仿真方法具有明显的优势。本文基于COMSOL Multiphysics有限元仿真软件,建立内部带有液压管和燃油管的燃油箱系统模型。通过电-热耦合仿真考察雷电流在燃油箱上的传导路径,根据电流分布及温度分布给出成为潜在点火源的位置。进而对比研究了两端是否屏蔽对燃油系统上雷电流物理特性的影响。仿真结果表明:飞机燃油箱系统遭受雷击时,成为潜在点火源的位置有卡箍边沿、17号肋与燃油管和液压管连接处、燃油管和液压管以及桁条上距离16号肋和18号肋上开孔较近的地方 ... Mehr lesen
引言:微波干燥过程涉及多物理场的耦合,物理过程十分复杂。不仅有被加热物质的形态改变,还有气态、液态和固态三相的相互作用。为了更清楚地理解微波干燥过程,本模型将电磁场、多相流和物理变形用相应的方程耦合到一起建模分析,并用相应的物理参数表征微波干燥过程。(图1) COMSOL Multiphysics® 的使用:借鉴微波加热接口土豆模型,添加气体和固体传热接口以及自定义方程,用方程和参数实现多物理场耦合。实验模型中,干燥物为土豆,且被视为多孔弹性介质。物质变形用相应的矩阵来表征。 结果:在仿真结果的基础上,利用家用微波炉干燥土豆,设计实验 ... Mehr lesen
A wide variety of near-field optical phenomena such as apertureless near-field scanning microscopy (ANSM) at optical and terahertz (THz) regimes and surface enhanced Raman scattering relies on the electric field enhancement at the end of a sharp tip. Achieving and controlling this ... Mehr lesen
This paper is a preliminary design study to develop a hybrid atmospheric icing sensor which have an adequate potential to detect an icing event, icing type and icing rate together with icing load. The physics to detect icing event and icing type have been numerically understood using ... Mehr lesen
The air gap is one of the most crucial part of magnetic circuits, especially in high-power inductors. It significantly modifies the parameters of magnetic devices by increasing the saturation current, linearizing B-H curve of magnetic circuit and causing a decreasing in the inductance. ... Mehr lesen
