本文旨在通过建立短弧灯的数值模拟模型，阐明短弧灯的能量平衡和传热过程。本文通过对自由燃烧电弧的数值模拟模型进行改进，建立了自由燃烧电弧的数值模拟模型，讨论了自由燃烧电弧对灯的辐射特性的影响。电磁现象本质上是在无限区域传播的。因此，有效地处理开边界是电磁场计算中的主要问题之一。本文介绍了能有效地进行有限域精确分析的正交化有限棱单元法。在这种方法中，有几个参数，以实现其高精度。作为参数之一，我们重点研究了参考点的位置设置对精度的影响。此外，还对计算的远区磁场的精度进行了评价。采用边界元法作为后处理，可以有效地获得该区域的高计算精度。
This study aims to clarify energy balance and heat transfer in short arc lamp by constructing numerical simulation model of short arc lamp. In this paper, influence of design of the lamp on radiation produced by the lamp is discussed by employing numerical simulation model developed by modifying numerical simulation model of free burning arc. The electromagnetic phenomena intrinsically spread over the infinite region. Thus, the e ffi cient handling of open boundary is one of the main issues in the electromagnetic field computations. This paper deals with the orthogonalized infinite edge element method which e ffi ciently performs precise analysis of the infinite region. In this method, there are several parameters to achieve its high accuracy. As one of the parameters, we focus on the reference point and investigate the e ff ect of its position setting on the accuracy. Fur-thermore, we also evaluate the accuracy of the calculated magnetic field at distance region. By applying boundary element method (BEM) as post-processing, it is found that the high computational accuracy in the region can be e ff ectively achieved.
