Buffet phenomena on supercritical airfoils were investigated both experimentally and numerically. The experiment was done for NACA0012 and KORN 75-06-12 airfoils using a high-speed Schlieren video tape recorder and pressure transducers. The analysis shows significant effects of the geometries and the Reynolds number. A 2-D N-S code was used to predict these phenomena. The result shows the macro-scale effects of airfoil geometry, Reynolds number and transition. A fine structure of the motion such as the periodic trailing edge pressure history was captured. The basic frequency of the buffet motion agrees well with the experiment.
