抄録

The efficiency of the water turbine is calculated using the static pressure measured on the side wall near the draft tube exit. The pressure decided from the water level just behind the draft tube exit is used if the pressure tap is not installed. Then, in this study, the open channel flow around the draft tube exit is researched experimentally using a model. The main results are obtained as follows. (1) The flow patterns in the open channel can be classified into four types. (2) The condition of the water level rise increasing to the downstream was clarified. (3) The difference between the static pressure head on the draft tube wall near the exit and the water level in the middle of open channel near the draft tube was given. Its maximum value reaches 0.12 V²_m/2g for low water levels and wide open channels.
