Abstract
In the present study direct numerical simulations (DNS) of Tollmien-Schlichting waves in attached boundary layers will be shown in comparison with local linear stability theory (LST). The goal of the investigation is a simulation of such modes in separated flow where LST is limited due to its basic approach. The method provides an improved understanding of the physical mechanisms behind the transition scenario in the linear as well as in the non-linear regime.
