title = "Global stability analysis of supersonic jets",
abstract = "Instabilities of supersonic jets are investigated by means of global linear stability analysis in both perfectly and under-expanded settings. In particular, the effects of the nozzle lip and of shocks on the instability mechanism are explored. Explicit representation of the nozzle within the computational domain gives rise to absolute instability via a coupling between the Kelvin-Helmholtz mode and the upstream-traveling acoustic wave in the vicinity of the nozzle lip. The presence of shock cells in under-expanded jets dampens the amplification of the instabilities. Nevertheless, the mechanisms of absolute instability are qualitatively similar for both fully expanded and under-expanded jets.",
