| Abstract: | Flow in a cross water turbine is more difficult to calculate than that of other shaft symmetry inflow type turbines, because the flow in the runner, that enters non-symmetrically from a nozzle, is unsteady even it is observed on the relative coordinate system. And the free surface in the runner also makes the analysis difficult. In this study, the flow in the runner and nozzle is solved simultaneously on the basis of absolute coordinate system. This flow is assumed to be unsteady Euler's one, and is analysed by MAC method. The time marching is made using implicit method of Crank-Nicholson and a new method of boundary condition on walls is developed. |
