The Role Of Kinetic Fluctuations in Laminar-Turbulent Transition of High-Speed Boundary-Layer Flows

Abstract

Perform comprehensive theoretical studies of the kinetic fluctuations(KF) induced transition in order to evaluate the upper bound of transition-onset for high-speed boundary layers in practical ranges of free-stream parameters including real gas effects. This effort will include, a) development of the KF receptivity model for chemically reacting gas mixtures; b) integration of the KF receptivity model into the framework of amplitude method and prediction of the upper bound of transition onset associated with thermal noise; and c) performing parametric studies of the KF-induced transition for practical ranges of free-stream parameters.
