To clarify the running characteristics in oscillating flow of a cross-flow turbine with two axisymmetric nozzles, experiments are carried out using a turbine test equipment in which wavelike up-and-down oscillating flow conditions are simulated. On the other hand, the dynamic characteristics of this turbine are calculated numerically on the basis of experimental data obtained from experiments in steady one-way flow conditions. The experimental results are compared with the numerical results and good agreement between them is demonstrated. Furthermore, the effects of load control and period of oscillating flow on the running characteristics are investigated.
