Kurzfassung
The goal of this study is a numerical investigation of the effect of rippled Surfaces on transition of laminar-wing flow by Tollmien-Schlichting (TS) waves. This will provide a numerical tool for the prediction of dominating physical mechanisms. Numerical studies of different accuracy and effort are expected, starting from linear stability theory (LST) in comparison with direct simulations of TS-waves, basic studies of flat plate with sinusoidal perturbations of small amplitude and large wave-length, as well as spacial investigations of TS-modes on a laminar profile with realistic surface-waviness
