| Abstract: | In this paper, a numerical solution for the calculation of the oscillations of water levels in surge chambers . Iteration was used to solve the implicit differential difference equations changed from the basic unsteady flow equations, which is able to be realized in computers with high precision. All kinds of water head losses and the working state of gradual opening or closing of guide blades will be considered. The method is suitable for the calculation of the oscillations of water levels in throttled surge chambers, cylinder surge chambers, as well as two-surge-chamber system. |
