Abstract
Laminar-turbulent transition of quasi-three-dimensional boundary-layer flows is investigated by nonlinear nonlocal instability theory based on parabolized stability equations (PSE). A strong TS-CF interaction scenario is described, which leads to a rapid rise in skin-friction coefficient indicating imminent breakdown of the laminar flow. The CF-CF interaction studies reproduce amplitude saturation observed in experiment, but do not provide an explanation for the final breakdown in crossflow-dominated boundary layers yet.
