Global Stability Analysis of the Interaction Between a Longitudinal Vortex and an Oblique Shock Wave

In this study, the interaction of a longitudinal vortex with an oblique shock was studied numerically. A global stability approach used to investigate onset unsteadiness due breakdown. For purpose, steady and unsteady laminar flow simulations were performed. exponentially decaying tangential velocity profile, so-called Erlebacher vortex, introduced into field by modification inflow boundary, while created ramp in supersonic flow. Parametric studies concerning influence axial deficit component on Several amplified eigenmodes could be identified it shown that frequencies predicted analysis reasonable agreement dominant observed simulations.
