Code-verification techniques for hypersonic reacting flows in thermochemical nonequilibrium

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). (C) 2020 Elsevier Inc. All rights reserved.

The study of hypersonic flows and their underlying aerothermochemical reactions is crucial for the design and analysis of vehicles entering and exiting Earth's atmosphere. Computational physics codes can simulate these phenomena, but verification is essential to ensure their accuracy and credibility. This paper presents code-verification techniques for hypersonic reacting flows in thermochemical nonequilibrium, demonstrating their effectiveness on the Sandia Parallel Aerodynamics and Reentry Code (SPARC).
