Abstract

The mechanisms of buffet are investigated by analyzing the flow over a DRA 2303 supercritical airfoil using time-resolved stereo particle-image velocimetry (TR-SPIV) in the trailing edge region and pressure measurements on the surface of the airfoil. The freestream Mach number is \(M_{\infty } = 0.73\) and the angle of attack is \(\upalpha = 3.5^{\circ }\) since under these conditions a distinct buffet flow occurs. To further study the influence of airfoil oscillations on the buffet flow and the occurrence of the lock-in of the buffet frequency into prescribed frequencies, the airfoil model undergoes forced oscillations near the natural buffet frequency.
