Titel:
Primary and Secondary Stabilityanalysis of a Three Dimensional Boundary-Layer Flow
Autor(en):
T. Fischer, U. Dallmann
Zusammenfassung:
A three-dimensional, incompressible boundary-layer flow is investigated theoretically with respect to primary and secondary instability. These investigations accompany a basic transition experiment, which is being performed at the DLR in Göttingen. Primary stationary and secondary non-stationary disturbances are used to model lhe measured mean flow and the velocity fluctuations in the early transition regime. Good agreement of the theoretical results with the experimental ones, especially concerning the spatial distribulion of the rms fluctuation within the boundary layer and along the flat plate is obtained by utilizing a secondary rather than a primary stability analysis.
