Hypersonic Flight

Submission status
Closed
The ExiF topical collection comprises 18 articles encompassing various aspects of hypersonic flight. Crucial to our understanding of high-speed flows is the development and improved analysis of ground-test facilities (Collen et al. 2021; Turchi et al. 2021; Cruden et al. 2021) as well as advances in relevant diagnostic and data analysis techniques (Miles et al. 2021; Shekhtman et al. 2021; Kovacs et al. 2022). Investigations of hypersonic boundary-layer instability and transition, primarily focusing on the behavior of the second mode for various surface geometries and wall conditions, are well represented in the works of Gragston et al. (2021), Butler and Laurence (2021), Oddo et al. (2021), Lukashevich et al. (2021), and Siddiqui et al. (2021), while studies of turbulent hypersonic boundary layers appear in Hopkins et al. (2021) and Williams et al. (2021). The contributions of Gülhan et al. (2021), Running and Juliano (2021), and Threadgill and Little (2022) concentrate on the important problems of shock-wave/boundary-layer interactions and shock–shock interactions (SSI), while Cardona et al. (2021) extend the study of SSI to the rarefied regime. Investigations of the free-flight aerodynamics of single (Seltner et al. 2021) and multiple (Whalen and Laurence 2021) bodies, relevant to space debris reentry and meteoroid fragmentation in the atmosphere, are also included in the collection; free-flight experiments on a large scramjet model are documented in Tanno and Tanno (2021).
