In this paper, we present direct comparisons of experimental results on transition in wall-
bounded flows obtained by flow visualizations, hot-film measurement, and particle-image …

The effect of high levels of free-stream turbulence on the transition in a Blasius boundary
layer is studied by means of direct numerical simulations, where a synthetic turbulent inflow …

The instability of the three-dimensional high-shear layer associated with a near-wall low-
speed streak is investigated experimentally. A single low-speed streak, not unlike the near …

Recent theoretical, numerical, and experimental investigations performed at the Department
of Mechanics, KTH Stockholm, and the Department of Mechanical Engineering, Eindhoven …

This paper presents theoretical results on the instability of a Blasius boundary layer
perturbed by Klebanoff modes (ie the low-frequency streaks known to be induced by free …

Wall turbulence is encountered in many technological applications as well as in the
atmosphere, and a detailed understanding leading to its management would have …

The interaction between two localized disturbances is analysed in a subcritical channel flow
through direct numerical simulations. The initial perturbations are in the form of two pairs of …

Experimental findings show that transition from laminar to turbulent flow may occur also if the
exponentially growing perturbations, eigensolutions to the linearised disturbance equations …

The temporal evolutions of small, streamwise elongated disturbances in the asymptotic
suction boundary layer (ASBL) and the Blasius boundary layer (BBL) are compared. In …

Die Untersuchungen des laminar-turbulenten Ubergangs, der sogenannten Transition, von
Grenzschichten angeströmter Körper erstreckt sich nach den vielfältigen …
