ディフューザーと平板翼の自励振動を利用した発電機の開発

When wind flows through the slats of a window blind, self-excited vibration sometimes occurs, which generates a high frequency noise. We have attempted to use this phenomenon to generate electricity. This paper reports our investigation of the effects of a diffuser which is attached to power generator. It was shown clearly in the experiment and the simulation that wind velocity becomes faster by a diffuser. According to this effect, a production of electricity increases at low wind velocity.
