抄録

There exists a certain leakage flow in general after the turbine gate has closed in practical hydraulic plants. The leakage flow influences on the oscillatory pressure wave form of the pressure-time diagram after the closing motion of the gate has stopped. In this paper, assuming an ideal pressure change, it is indicated that the oscillatory pressure wave is damped rapidly by the existence of leakage flow. Moreover the relation with Gibson Method under these condition is checked.
