Global instability analysis is used to investigate the effects of extended regions of laminar flow on both unswept and swept infinite-span wings. The formulation is based on the Reynolds-averaged N...

Surface step effects on boundary-layer transition are modeled using a variable N-factor method for transition dominated by Tollmien–Schlichting instabilities. Experimental correlations provide a bo...

Effects of gaps (rectangular surface cavities) on boundary-layer transition are investigated using a combination of linear stability theory and experiments, for boundary layers where the smooth-surface transition results from Tollmien–Schlichting (

Approaches to transition prediction are considered within the context of applications to aircraft, where surface-induced distortions are an integral part of the boundary-layer flow. Different routes to transition are discussed as a function of the ty

Global stability analysis is used to analyse the onset of transonic buffet on infinite swept and unswept wings. This high-Reynolds-number flow is governed by the unsteady Reynolds averaged Navier–Stokes equations. The analysis generalizes earlier s

Surface-roughness and free-stream-turbulence effects on crossflow-instability transition are investigated experimentally and theoretically. A model baseflow is established and shown to be well predicted by boundary-layer analysis. Surface roughness i
