Code-Verification Techniques for Hypersonic Reacting Flows in Thermochemical Nonequilibrium [PDF]
Journal of Computational Physics, 425 (2021), 2020 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.

Electrical Discharges in Hypersonic Flows [PDF]
The Physics of Fluids, 1960 In order to study the interaction between an electrical current and a high-speed flow, experiments are being conducted with low-current electrical discharges in the 5 x 5-in. test section of the GALCIT hypersonic tunnel, in which continuous uniform flows are produced at M = 5.8 and total temperatures = 150°C.
