Research Abstract |
This study was conducted to develop a large high-speed shutter that can be used with a large size fluctuating wind direction tunnel. The tunnel is expected to be able to simulate the fluctuating wind direction characteristics of natural wind. The tribally manufactured shutter could decrease the wind speed within 0.2 second over large area of the test section. The developed shutter is thought to be applied with a large size fluctuating wind direction tunnel. Also a pressure measurement method was confirmed to be effective that can remove the effects of the static pressure fluctuation such as that with wind direction change of fluctuating wind direction tunnel.
