Abstract

To determine allowable tolerances between successive suction-panels at hybrid laminar wings with suction-surfaces, direct numerical simulations of Tollmien-Schlichting waves over different steps are carried out for realistic suction-rates on a wind tunnel configuration. Simulations at given suction-panel positions over for-ward and backward facing steps are carried out by the use of a high-order method for the DNS of TS-wave growth. Comparisons between high-fidelity DNS-results and quick linear stability calculations have shown capabilities and limits of the well validated LST design-approach.
