On Nonlinearity of Transitional Boundary-Layer Flows

On Nonlinearity of Transitional Boundary-Layer Flows

This paper focuses on two specific effects concerning the nonlinearity of transitional boundary-layer flows: the generation of turbulent spots in a flat-plate flow, and the nonlinear behaviour of laminar separation bubbles associated with the short-scale instability of the separated layer. A compila...

Beschreibung
Zusammenfassung:This paper focuses on two specific effects concerning the nonlinearity of transitional boundary-layer flows: the generation of turbulent spots in a flat-plate flow, and the nonlinear behaviour of laminar separation bubbles associated with the short-scale instability of the separated layer. A compilation of results from several experimental studies is given.
