Towards Natural Transition in Compressible Boundary Layers

Abstract

This final report concerns the results obtained in the project titled: "Towards natural transition in compressible boundary layers", with Grant number FA9550-11-1-0354-P00002, in the period 30-09-2011 to 29-03-2016, with Dr. James M. Filler up serving as program manager. In this project, a DNS code was developed to investigate problems on transition in compressible boundary layer on a plate. Code validation test were performed for linear and nonlinear stages of transition, in incompressible and compressible regimes. The focus of the present work is to investigate natural transition in compressible subsonic boundary layer modeled by wave packets; and perform a preliminary study of transition generated by white noise.
