| Research Abstract |
The energy collected by a small-scale fall difference micro hydroturbine is converted into the electrical energy with the dynamo. The net head was assumed to be 1.5m, and flowing quantity and the hydroturbine efficiency by runner's angle difference were clarified. The same size as the diameter of the runner corn was tested. The effect was admitted in the removal of the air-entraining vortices as for this, and the augmentation of the power output was confirmed. It was able to be confirmed that the air-entraining vortices was prevented by using corn even if flowing quantity was a little, and the water mill efficiency did not decrease.
