Abstract
Flows around an elastic plate with a pitching motion in a uniform flow are visualized. The pitching motion is one cycle of oscillaion with constant angular velocity. The flow patterns are visualized by the tracer techniq using Al-pouder.
In the experriment, the amplitude and frequency of oscillaion, velocity of the uniform flow and the length and flexural rigidity of plate are changed. Flow patterns around a pitching elastic plate are compared with that of a rigid plate.
