Beyond classical similitude: group theoretic extrapolation of hypersonic stagnation-point boundary layers
Shujaut H. Bader, Daniel J. Bodony
Motivated by the need to extrapolate the results from ground-based experiments to the conditions of high-speed flight, we present the Lie equivalence symmetry analysis of the hyper…

Surface instabilities in laminar compressible boundary layers with sublimation
Blaine Vollmer, Alberto Padovan, Daniel J. Bodony
Surface patterns on ablating materials are observed in high-speed ground and flight tests, but the mechanisms behind their formation are not known. In this paper, the origin of sur…
