Global Modal and Non Modal Instability Analyses of Shock Induced Separation Bubbles
Abstract
Following an in-depth literature survey, work in this grant was performed along five paths: (i) two-dimensional direct numerical simulations which delivered the steady laminar base flows analyzed, (ii) analytical generation of meshes on which accurate instability analysis results could be obtained, (iii) development of LiGHT (Linear instability for Global, Hypersonic Transition), a massively parallel large eigenvalue and singular value problem solver used to (iv) perform modal and non-modal, 2- and 3D global linear instability analyses and (v) derivation and programming of the interactive boundary layer / triple-deck equations for base flow and instability analysis of supersonic flows.
