概要
- 論文の詳細を見る
An accurate photographing and image processing system for capturing the high-speed periodic motion of shock waves in unsteady transonic flow cascades is developed using a videocamera with a moderate frame rate instead of using a high-speed videocamera. The feasibility for generating successive pictures in one period whose frequency is up to 500Hz is confirmed. Behavior of shock waves is clarified in the range up to 200Hz. Although the amplitude of shock wave displacement does not change much within the range of the present experiment, the phase lag relative to the blade oscillation reaches around π/2 as the blade oscillation frequency increases to 200Hz.
