Hypersonic boundary layer instabilities (INVITED)
Abstract eng: Our current activities focus on nonlinear parabolized stability equation (NPSE) and bi-global stability analysis of the crossflow, second-mode, and secondary instabilities associated with hypersonic geometries such as the yawed straight cone and the elliptic cone. A predictive NPSE formulation (EPIC) has been developed in-house for modeling of the evolution of instabilities, including the stationarycrossflow-vortex path and the variation of the spanwise wavenumber in the streamwise direction. Multiple instabilities and secondary instabilities are mapped, and these studies are extensively verified and validated with lessons learned provided.
