Abstract
I studied an aeration system using a simple pump driven by a Savonius wind turbine installed on a float. This simple pump uses centrifugal force to draw water from the bottom layer to the surface of a pond. Based on previous studies, I designed and produced a demonstration model, 1700 mm high, measured from the surface of the water of high, 2300 mm long and 2300mm wide. The floating and the rotational performance of the model have been confirmed. By improving the waterproof mechanism of the shaft and bearing, and examining the material, rotation from a lower wind speed of 5m/s has been achieved. In addition, adjusting the diameter of the pipes, which are components of the simple pump, revealed that the torque characteristics of the pump can be adapted to the characteristics of a Savonius wind turbine.
