论文摘要
在设计和分析地球大气层的车辆的设计和分析中,对高超音速流及其潜在的空气化学反应的研究尤为重要。可以使用计算物理代码来模拟这些现象。但是,对这些代码的验证对于证明其信誉是必要的。迄今为止,很少有用于验证模拟高超音速流的代码的方法,尤其是在热化学无序中反应的流动。在本文中,我们介绍了代码验证技术,用于验证热化学非平衡中高超音速反应流中的空间精度和热化学源项。我们证明了这些技术对Sandia平行空气动力学和重新进入代码(SPARC)的有效性。
The study of hypersonic flows and their underlying aerothermochemical reactions is particularly important in the design and analysis of vehicles exiting and reentering Earth's atmosphere. Computational physics codes can be employed to simulate these phenomena; however, verification of these codes is necessary to certify their credibility. To date, few approaches have been presented for verifying codes that simulate hypersonic flows, especially flows reacting in thermochemical nonequilibrium. In this paper, we present our code-verification techniques for verifying the spatial accuracy and thermochemical source term in hypersonic reacting flows in thermochemical nonequilibrium. We demonstrate the effectiveness of these techniques on the Sandia Parallel Aerodynamics and Reentry Code (SPARC).
