Theoretical and Computational Studies of Stability, Transition and Flow Control in High-Speed Flows

Abstract

A comprehensive study of stability and receptivity of hypersonic boundary layers has been carried out. The main results of the project: (1) Mathematical method of the multimode decomposition for three-dimensional perturbations in compressible boundary layers has been developed. The method provides analysis of experimental and computational results for modes of discrete and continuous spectra. (2) Theory of boundary-layer receptivity was developed for roughness-induced perturbations in incompressible and compressible boundary layers. (3) The transient growth phenomenon in compressible boundary layers over flat plate, sphere, and sharp cone has been studied. The work was accompanied by development of solvers for these geometries.
