论文摘要
我们提出了一种通用解决方案，用于以恒定速度和恒定温度向观察者移动的纯粹吸收平板前面的辐射强度。通过通过平板将实验室辐射传输方程整合到观察者来获得解决方案。我们介绍了我们的基准测试和KULL模拟代码的结果，以朝着观察者向观察者移动的2％光速。我们证明，随着频率分辨率的提高，忽略传输方程中某些材料运动校正项可能会导致20-80％的误差。我们的结果还表明，我们的基准可以在实施材料运动校正时确定潜在的错误。
We present a general solution for the radiation intensity in front of a purely absorbing slab moving toward an observer at constant speed and with a constant temperature. The solution is obtained by integrating the lab-frame radiation transport equation through the slab to the observer. We present comparisons between our benchmark and results from the Kull simulation code for an aluminum slab moving toward the observer at 2% the speed-of-light. We demonstrate that ignoring certain material motion correction terms in the transport equation can lead to 20-80% errors with the error magnitude growing as the frequency resolution is improved. Our results also indicate that our benchmark can identify potential errors in the implementation of material motion corrections.
