The figures 1 and 2 show the instantaneous velocity vector fields at the conditions written on the plots. Figure 1 shows the velocity field without blowing at the fluidic trailing edge device and with buffeting and strong separation, while figure 2 shows a velocity field realized at the same CL with blowing at 1.5 bar with a lower angle of attack, which inhibits buffeting and reduces drag. In figure 3 density gradient field visualization by BOS shows the induced field caused by the blowing device and the flow separation at the trailing edge during transonic buffeting.
