In this paper, it was investigated wind pressures acting on a circular cylinder with rotors. The basic motive of this research was how to increase momentum of air flows passed around a circular cylinder in ordinary wind tunnel. The authors assumed it may be possible changing the air flows passed a circular cylinder by rotors. Also, it was assumed that rotors can simulate the flow re-attached to the surface of the cylinder. A pair of rotors was installed in a circular cylinder to verify those assumptions. Wind tunnel experiment of application of rotors to change air flows passed a circular cylinder was performed. Wind pressures acting on a circular cylinder equipped with rotors were measured to investigate changes of air flows. The ratio of rotor circumferential velocity to wind speed was used as a parameter for investigation of rotor's effects. As the results of the experiment, the wind pressures on the circular cylinder were significantly affected by the velocity ratio.
