三维俯仰转动和俯冲运动翼型的平移边界层立体PIV测量
This student research project deals with the investigations of the flow phenomena over athree dimensional moving airfoil. The complex motion apparatus was set up to create apitching, plunging and rolling movement of a two dimensional wind tunnel model. The mainobjective was to determine the position of transition with respect to the phase angle andspan-wise distribution. The campaign focussed Stereo PIV measurements, but also MiniTuft-, Oilfilm- and SSLCC- Techniques, contributed to the results. It can be shown that theflow field is not dominated by side-wall effects, while the transition oscillates correspondingto the spanwise variation of the heaving cycle.
