Journal ArticleDOI
On the breakdown of boundary layer streaks
TL;DR: In this article, a scenario of transition to turbulence likely to occur during the development of natural disturbances in a flat-plate boundary layer is studied, which is based on a linear Floquet expansion and focuses on the temporal, inviscid instability of these flow structures.
Journal ArticleDOI
Transition in boundary layers subject to free-stream turbulence
TL;DR: In this article, 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 is obtained as superposition of modes of the continuous spectrum of the Orr-Sommerfeld and Squire operators.
Journal ArticleDOI
Steady solutions of the Navier-Stokes equations by selective frequency damping
TL;DR: In this article, the Navier-Stokes equations in globally unstable configurations are computed by damping the unstable (temporal) frequencies, which is achieved by adding a dissipative relaxation term proportional to the high-frequency content of the velocity fluctuations.
Journal ArticleDOI
Delaying transition to turbulence by a passive mechanism.
TL;DR: This work takes a second approach consisting of keeping the boundary layer laminar as long as possible by forcing small optimal perturbations, and shows that by using this passive control technique it is possible to sensibly delay transition to turbulence.
Journal ArticleDOI
Experimental and theoretical investigation of the nonmodal growth of steady streaks in a flat plate boundary layer
TL;DR: In this article, an experimental and theoretical investigation aimed at describing the non-modal growth of steady and spanwise periodic streamwise streaks in a flat plate boundary layer is presented.
