Abstract

The characteristics are studied of the wind generated by a prototype of a new type wind tunnel that can change the wind direction, which is called as a fluctuating wind direction tunnel (FWDT). The FWDT consists of eight inflow and eight outflow wind ducts with shutters, which are radiately located around the test section. By opening only one or two sets of inflow and outflow ducts, wind blows in that direction. With this FWDT, nearly 180 degree fluctuation of the wind direction is possible. Now ten shutters are operated by linear motors and they can be controlled by a computer; it can produce 90 degree wind direction change at most. The best shutter opening and closing timing was studied with smaller wind speed fluctuations during the wind direction change.
