Resonant growth of three-dimensional modes in trnsitioning Blasius boundary layers

By carefully controlled phase-coupled input of simultaneous two- and three-dimensional disturbances, the nonlinear evolution and breakdown of the laminar flow in a boundary layer was examined. This involved the generation of plane Tollmien-Schlichting waves and pairs of oblique waves so as to promote near-resonance conditions which have been theoretically shown to lead to the rapid development of three-dimensionality in unstable boundary layers
