Instabilities in hypersonic boundary layers under the influence of high-temperature gas effects

Research output: Chapter in Book/Report/Conference proceedingConference contributionpeer-review

Abstract

Investigations on the spatial evolution of instabilities for hypersonic boundary-layer flows on a flat plate with dissociation are presented. A higher order compact numerical scheme allows for the detailed investigation of the linear and the non-linear evolution of the disturbance waves in the presence of chemical reactions. Compared to the ideal-gas case, lower temperatures in the boundary-layer are present. The three-dimensional disturbance behaviour is experiencing slight damping in the linear regime compared to equilibrium results. High-level disturbances can also lead to local shocklets that are treated with a hybrid ENO-scheme. Experiments for qualitative validation of the results at elevated Mach numbers are available by Mironov.
