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 a
three dimensional moving airfoil. The complex motion apparatus was set up to create a
pitching, plunging and rol领 movement of a two dimensional wind tunnel model. The main
objective was to determine the position of transition with respect to the phase angle and
span-wise distribution. The campaign focussed Stereo PIV measurements, but also Mini
Tuft-, Oilfilm- and SSLCC- Techniques, contributed to the results. It can be shown that the
flow field is not dominated by side-wall effects, while the transition oscillates corresponding
to the spanwise variation of the heaving cycle. 德国LaVision PIV/PLIF粒子成像测速场仪 三维立体PIV
