Abstract

The results of experiments in a low-turbulence subsonic wind tunnel confirming the possibility of a significant attenuation of the cross-flow velocity and the intensity of instability of stationary vortices in this flow due to the body-force effect on a three-dimensional boundary layer are presented. The unidirectional body force above a significant area of the streamlined surface was generated by a multidischarge actuator based on the surface dielectric barrier discharge.
