Pressure distributions on the blade surfaces of a Savonius rotor with and without rotation are measured for various rotor angles and tip-speed ratios, and the power mechanism is discussed based on the result. The torque-producing mechanism of the rotating rotor is strongly contributed to by the large negative pressure region formed on the convex side of the advancing blade, suggesting the Coanda-like flow pattern shown in the flow visualization experiment, while that of the still rotor is mainly due to the stagnation effect on the concave side. The torque and the power performances estimated from the present pressure measurement agree approximately with the previous results by direct torque measurement, which shows the approximate two dimensionality of the flow field near the rotor.
