Control of flow separation by dynamic excitation of the free shear layer,d blowing through a narrow slot close to the leading edge of the airfoil. A small cavity below the slot was connected to a horn-driver providing periodic pressure fluctuations to drive the flow through the slot. The present research confirms the results of previous studies that the mechanism for圆桶 发表于 2025-3-30 14:05:19
On Active Control of Boundary Layer Instabilities on a Wing,in a reduction of the viscous friction drag. One less known approach is the reduction of natural occurring instability waves, so called Tollmien-Schlichting-waves (TS-waves) of a laminar boundary layer by means of superposition with artificially excited canceling waves.
