The stabilization of Tollmien-Schlichting (TS) waves in a spanwise modulated Blasius boundary layer has been experimentally verified in the MTL wind tunnel at KTH. The alternating high and low speed streaks were created by regularly spaced cylindrical roughness lements mounted on the flat plate. It is shown that the larger the streak amplitude is the larger is the damping effect of the TS-waves, which is in agreement with recent theoretical work.

Abstract
The stabilization of Tollmien-Schlichting (TS) waves in a spanwise modulated Blasius boundary layer has been experimentally verified in the MTL wind tunnel at KTH. The alternating high and low speed streaks were created by regularly spaced cylindrical roughness lements mounted on the flat plate. It is shown that the larger the streak amplitude is the larger is the damping effect of the TS-waves, which is in agreement with recent theoretical work.File in questo prodotto:
