サボニウス風車の翼に作用する力の測定と翼まわりの流れの可視化

抄録

For the purpose of clarifying the mechanism of rotation of Savonius rotors, ones which have two semicylindrical blades are studied experimentally. The force acting on a blade is measured in a water two tank for both cases where a rotor is at rest and rotated. The flow around a rotor is observed by using aluminum powder floating on the water surface. Although the Savonius rotor is classified into a resistance type, the lift produces the torque in a pretty wide range of angle relative to the flow.
