Receptivity of blunt flat plate hypersonic boundary layers to spanwise transverse wave disturbances and surface roughness

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

We investigate the evolution of post-leading-edge low-frequency transverse perturbations in hypersonic boundary layers. Transverse disturbances are an important source of streamwise vorticity receptivity process in high speed boundary layers and the present work is an attempt to better understand this phenomenon. We consider the growth of perturbations close to the leading edge relevant for receptivity analyses. Perturbation growth due to surface roughness is also quantified. Both, sharp and blunt leading edge wedges are considered in the analysis.
